Part 1: Sonar Controls
1.1 Hand ControlAll sonar adjustments are conducted through the hand control.
1.1.1 Trigger SwitchThe trigger switch will move the cursor from the sonar screen to the selection screen when adjustments are needed. After adjusting, the trig-ger switch will return the cursor back to the sonar screen.
1.1.2 Four-way Control SwitchThe four-way control switch will move the cursor up/down, left/right on the sonar screen. By placing the cursor on a target both horizontal and vertical measurements are logged in the space noted by the arrows, center right of screen.When the cursor is in the selection screen the four-way switch will move the cursor up/down to the item for adjust-ment. Moving the four-way switch left/right will make the change.
1.2 Switch Panel Both the sonar and the hoist are independent of one another. The sonar has its own on/off switch and the hoist has its own down/up switch.

1.2.1 Sonar On/Off SwitchThe sonar on/off switch is fused with a 10 amp slow blow (MDL) fuse. This fuse is inline with a fuse on the power supply board inside the computer box. The power supply fuse is 7.5 amp fast blow (AGC) for 12 or 24 volt operation.
1.2.2 Hoist Down/UpTo lower the hoist push down on the hoist switch. If the hoist is hydraulic a green light will glow when the motor is running and turn off when the motor stops. The green light is not used with the lead screw hoist systems. On all systems a red light will stay on as long as the hoist is down.
1.2.3 Hoist FuseOn lead screw hoist systems the fuse used is MDL (slow blow) 3.2 amp. On hydraulic systems use AGC (fast blow) 1 amp. If the fuse is open the hoist will not go down.
1.3 Selection ScreensThere are four selection screens where adjustments are made. Each adjustment can be viewed as the sonar runs to maximize target detection. The four selection screens are titled as; Wesmar 395, Sonar, Profiler and Local. To make an adjustment to the sonar, trigger once with the hand controller. This will activate the Wesmar 395 selection screen. To enter any of the other three selection screens push up or down on the four way switch until SET UP is highlighted. Push left or right on the four way switch for: S = Sonar, P = Profiler, L = Local then trigger with the hand controller. After adjustments are made, trigger the hand controller to move the cursor back to the sonar screen.
1.3.1 Wesmar 395 Selection ScreenWesmar 395 is the first screen to appear when triggered with the hand controller. All of the adjustments are for sonar with the exception of NEAR P and FAR P, which are gain adjustments for profile.

RANGESonar range can be increased or decreased by push-ing the four-way switch on the hand controller to the left or right. Range units; meter, fathom, feet are selected in selection screen Local.
TILTTransducer can tilt up +4 degrees above the hori-zontal to –90 degrees straight down. A 0 degree tilt will center the sound beam horizontally.
CENTERMove the sector in nine-degree steps around the screen.
REVERSEReverse will change the direction of scan. This is the recommended method when following fast moving tagets such as tuna and game fish. There are two ways to reverse scan.1. Highlight reverse, push the four-way switch to the left or right. Each time the four-way switch is pushed scan will reverse.2. Highlight reverse, pull the trigger to reverse scan. Pull the trigger again to highlight reverse then pull the trigger to reverse. As fast as one can pull the trigger two times the scan will reverse.
THICKThickness will work in sonar screen #1 only. Thick-ness is scanning up and down through the target or over the bottom. This is an excellent way to see if there are more fish under the fish schools that were scanned in the horizontal or to determine the vertical size distribution of the school. Thickness can also be used to profile the bottom out in front to measure depth when entering uncharted waters.
There are two ways to activate thickness.1. Highlight thick. Wait for the horizontal scan to pass through the target. Pull the trigger, the transducer will stop and start to scan up and down through the target. The vertical display will show in the lower right of the screen. As the target
5
moves the thickness mode of operation can move to follow the target by pushing the four-way switch to the left or right. Reverse can also be used to change direction of the vertical scan. To end the thickness mode pull the trigger twice.2. Highlight thick. Push the four-way switch to the left or right. The transducer will stop and start to scan up and down. Push the four-way switch a second time to end thickness mode. Note: Entering thickness mode by using the four-way switch will disable the ability to change bearing. Bearing can only be changed when entering thickness by using the trigger switch.
SECTORSelect the area to be scanned from full circle; 360 degrees down to 11 degrees.
SPEEDControls the scanning speed of the sound beam. Speed 1 is for fine resolution. Speed 4 is for fast up-date. Faster speeds may lose single fish targets.
ZOOM In Screens 1, 2 and 3 the cursor can be used as a magnifier. By activating zoom the target under the cursor will magnify for a close inspection. The perimeter line around the cursor indicates the magnified area.
NEAR SNear gain adjustment for sonar. Gain numbers run from 0 to 100. Regardless of range the near gain has more control over targets from the center of the screen to half way out. Adjust for best presen-tation.
FAR SFar gain adjustment for sonar. Gain numbers run from 0 to 100. Regardless of range the far gain has more control over targets from half way to the end of screen range, or the last half of range selected. Adjust for best presentation.
NEAR PNear gain adjustment for profile. Profile gains are separate from sonar. Gain numbers run from 0 to
6
100. Regardless of range the near gain has more control over targets from the center of the screen to half way out. Adjust for best presentation.
FAR PFar gain adjustment for profile. Gain numbers run from 0 to 100. Regardless of range the far gain has more control over targets half way to the end of the screen range. Profile is frequently used to profile the bottom. FAR P adjustment is used to bring bottom markings in strong.
SET UPSet up provides access to three other selection screens; SONAR, PROFILE, LOCAL. To acti-vate one of the three screens first trigger the hand controller once. The WESMAR 395 screen will appear. Move the four-way switch up or down to set up. Push the four way switch left or right to highlight the selection screen you want to go to. Trigger the hand controller for the second time to view the screen.
By triggering the hand controller the third time will place the cursor back into the sonar display.
COLOR BARSThere are two color bars, one on top of the other. The top color bar represents the colors and thresh-old for sonar. The bottom bar represents the colors and threshold for profile. Adjustments are found in SONAR and PROFILE.
1.3.2 SONARSonar refers to horizontal scan around the vessel. This is different from profile where the transducer scans from side to side beneath the vessel. To maximize target detection both sonar and profile each have their own selection screen. Adjustments can be different from the other. The SS395 will store the settings and recall them the next time the system is turned on. However, if there is more than one application (more then one fishery) a record of the settings should be kept.
RANGESame range adjustment under Wesmar 395. For
7
convenience sonar range is repeated.
PULSEPulse refers to the transmit pulse or the time the transmitter is on pushing sound energy into the water. A long pulse, 100% is best for long-range detection. Selecting shorter pulse lengths will increase range resolution separating two targets close together. As the pulse length is shortened, near and far gains will need to be increased.
SECTORSame sector adjustment found in the last selection screen, Wesmar 395. For convenience sector is repeated.
TVGTime Variable Gain offsets propagation loss as sound energy moves through the water. A target at long range will have a small echo than close to the vessel. In order for this target to mark the same color at different ranges the receive gain must increase proportionally with range. Propagation losses of sound energy will change with frequency, salinity, and the amount of plankton and algae in the water. Adjust TVG according to the frequency of the sonar.
Adjustment:160kHz set TVG to 400, span 200 to 600110kHz set TVG to 600, span 400 to 800 60kHz set TVG to 800, span 600 to 1000
Each 100 units will equal 250 ft or 75 meters of range. A setting of 400 will then equal 1000 ft or 300 meters. When using the blue background a gray ring will display on the screen equal to the TVG setting. Targets on the inside of the ring will be compensated for propagation losses where targets outside the ring will become stronger as the vessel approaches until the target cross over the gray ring.
SPEED
8
Speed will change the scanning speed of the trans-ducer. A speed of one will step the transducer in 1.8 degree steps, where a speed of four will step in 7.2 degree steps. A speed of one is considered regular scan with fine resolution where a speed of four yields a faster scan with lower resolution.
ENHANCEEnhance is one of three filters. Selections are from OFF to 5. Enhance will help in target recog-nition of individual targets such as tuna, salmon, and sports fish. If bottom typing for shrimp, turn enhance off.
FILTERFilter is the second of three filters. Filter is used to filter out unwanted returns and reduce clutter from the screen. Filter should be turned off when scan-ning for small targets. Use Filter when scanning for schools of fish and bottom typing
LIMITERThe third of the three filters. The limiter can be ON or OFF. When ON, interference from any other sonar/sounder equipment on board will not mark on the screen. This is accomplished by eliminating all targets that are not present in two consecutive transmits at the same range. The limiter is very effective; however, when scanning for individual targets it is recommend to turn the limiter OFF. When the limiter is ON there will be a (?) after ON to question the operator if this is the correct setting.
THRESHOr Threshold. Selections are from 1 to 4. In order for a target to display on the screen, the echo, after going through the receiver, must be strong enough to reach the colors. The colors can be raised or lowered. Lowering the threshold will display all targets including weak ones without adjusting gains. Raising the threshold will remove weak targets leaving only strong targets on the display.
DELETEDelete will remove targets colors weak to strong.
9
CLIPClip is a color stronger then red. Clip is primarily used for bottom typing to distinguish between, rock, sand, or muddy bottom. On hard bottom ad-just gains so bottom just marks in the clip color.
BACKBack or background is the color behind the targets on the screen. 1=Black, 2=Blue and 3=White.
Black can be used at night and during the day. At night the black background emits no light and the targets stand out in fine detail. For nighttime view-ing it is recommended to lower the brightness of the text or words on the right of the screen. To dim the text go to the LOCAL page and increase the number for TEXT. Blue and White are normally day time screen. A background color will increase the contrast making the target much easier to view. If small targets are of interest try the white back-ground and select 4 to 6 on PALETTE.
PALETTEPalette deals with target color brightness from blue to red. When using a low threshold the screen may by full of blue and green targets. Too much color on the screen may be distracting; however, the weak targets are telling the operator something about the area of search. Palette is a brightness scale that will dim target colors from weak to strong. Select a palette number that will dim the weaker targets without removing them from the screen. This helps in strong target recognition with less fatigue to the operator.
1.3.3 PROFILEProfile scans the transducer from side-to-side un-der the vessel like a pendulum of a clock. Profile expands bottom coverage not covered by down sounders. Because the sound beam is narrow resolution off the bottom is very good. The SS395 in profile will cover the bottom six times that of a down sounder without the loss of resolution. To optimize detection profile has its own adjust-ments.
10
When operating in split screen, SONAR settings are used when scanning horizontal. When the transducer moves to profile the PROFILER set-tings will be used. RANGEWhen profiling the bottom select a range equal to twice the depth. This will give full bottom coverage across the screen.
PULSEA long transmit pulse, 100% will deliver more power into the water then a short pulse. A short pulse has superior range resolution then a long pulse. When profiling for fish just off the bottom a short pulse should be selected. As the pulse length is shortened, near and far gains will need to be increased.
SECTORProfile has its own sector sizes with the center mark straight down.
TVGTime Variable Gain offsets propagation losses as sound energy moves through the water. These losses are compensated by the TVG setting. Losses are different with different frequencies.
Adjustment:160kHz set TVG to 300, span 200 to 600110kHz set TVG to 500, span 400 to 800 60kHz set TVG to 700, span 600 to 1000
SPEEDSpeed will change the scanning rate of the trans-ducer as it sweeps over the bottom. For good bot-tom detail use speed 1.
ENHANCEEnhance is one of three filters. Enhance will help in target detection of fish and objects on the bottom small in size.
FILTERFilter is the second of three filters. Filter is used to reduce clutter; however, too much filter will lower
11
·
the probability of detection of small targets.
LIMITERThe third of three filters. The limiter can be ON or OFF. Turning ON the limiter will remove inter-ference from other sonar/sounder equipment from the screen. Objects close to the bottom or on the bottom may not mark with the limiter ON. The limiter should only be used when large targets are of interest.
THRESHOr threshold. Selections are from 1 to 4. If set too high, only strong targets will be detected. If the threshold is set low the smallest of echoes will be detected. For bottom typing a low threshold setting is desirable.
DELETEDelete will remove targets colors weak to strong.
CLIPClip is a color stronger then red when selected. When bottom typing make the following settings. Select the clip color. Lower the threshold to 1. Turn ENHANCE to OFF. Turn FILTER to 5. When over hard bottom adjust the near and far gains so the bottom just marks in the clip color. All other bottom types will mark in cooler colors.
BACKBack or background is the color behind the targets on the screen. 1=Black, 2=Blue and 3=White.
Black can be used at night and during the day. At night the black background emits no light and the targets stand out in fine detail. For nighttime view-ing it is recommended to lower the brightness of the text or words on the right of the screen. To dim the text go to the LOCAL page and increase the number for TEXT. Blue and White are normally day time screen. A background color will increase the contrast making the target much easier to view. If small targets are of interest try the white back-ground and select 4 to 6 on PALETTE.
PALETTEPalette is a target brightness control. When ac-tivated screen targets will dim from blue to red. When using lower thresholds 1 or 2 the screen may be cluttered with targets. Rather then deleting the lower colors use PALETTE to lower the brightness of the weaker targets.
1.3.4 LOCALLocal are general adjustments that are not changed to often.
UNITSSelect; feet, meters or fathoms.
LANGUAGESelect the number that corresponds to the language of preference.
AUDIOThe hand controller has a built in speaker that will sound when targets are displayed on thescreen. For additional volume connect an external ampli-fied speaker to the audio line output jack on the computer control unit, see section 3.1.6 for more information. Audio is only activated after the first range ring. This will reduce any audio from noise that is around the boat. Audio is extended to the corner of the screen. Two types of audio are avail-able; Fish Alert and Modulation.
FISH ALERTFish alert is ideal for purse seining. When fish schools mark on the screen the alert will sound. Fish alert is only sensitive to the clip color. Colors other then clip will not trigger the fish alert. The size of schools that triggers the alert is determined by selecting 1 for small schools and 10 for larger schools. OFF will turn the fish alert off. MODULATIONModulation will sound on any size of fish target and or bottom. By deleting colors or changing thresholds the sound will follow the change. There are three selections of the modulation sound, M-1, M-2 and M-3. Both M-1 and M-2 will have the sound of the transmit pulse at the beginning of
the receive cycle. Modulation M-1 has a louder transmit sound then M-2. Modulation M-3 has no transmit sound, only the fish target will sound and or bottom will be heard.
VOLUMESpeaker volume selected from 1 to 5.
TEXTText will dim all the white lettering and range rings for night time viewing.
MARKSRange rings can be turned on or off.
SCREENThere are four fishing sonar screens available. Screen #1: Full circle sonarScreen #2: Split Screen sonar on top with bottom profile on bottom.Screen #3: Half screen bottom profile only. Can run with the soundome in the up positionScreen #4: Full screen down sounder. (Note: Sounder controls Down Sounder settings.)
BRIGHTBrightness will control the overall intensity of the display.
TUNINGAdjust frequency for the best target presentation with minimal noise. This adjustment changes the frequency of the transmitter and receiver. ADJUSTMENT:160kHz, set to 159kHz: span 156kHz to 162kHz.110kHz, set to 114kHz: span 108kHz to 117kHz. 60kHz, set to 60 kHz: span 57 to 62kHz.
UPDATEWhen new programs come available the software can be installed in the sonar computer board. Select UPDATE to transfer the new program to the trans-mit receive motor drive board no the hoist assembly. Can be used to restore the program if need be.13

2.1.1 Hand ControllerThe SS395 hand controller can be considered the sonar consolate where all adjustments are made. Its location should be easily reached when fishing. The hand controller has a 10ft, 3.0 meter cord with a connector at the end that mates to the bulkhead connect.
Would you like to have more than one hand con-troller? Three good locations would be the wheel house, flying bridge and/or the fish deck. By in-stalling the hand controller expansion box, part #64.00342.0, and three bulk head connectors part #64.10342.0 this will give you full sonar control from three locations.
2.1.2 Bulkhead Connector PanelThe bulkhead connector panel comes with a 10ft (3 meter) cable with a connector at the end. This connector will mate to the computer control unit or expansion box. To install the bulkhead connector,

make a hole in the instrument panel 1 3/4 inches (44.5 mm) in diameter. Attach the bulkhead con-nector plate to the instrument pnael using the holes in the four corners.
2.1.3 Computer Control UnitThe computer control unit is designed to fit under the instrument panel. There are three cables in the wheelhouse that connect to the computer control unit. Consider the length of these cables before selecting a lcoation to mount the computer control unit.
1. The cable from the bulkhead connector panel is 10ft ( 3 meters) long. it must reach the computer control unit.2. The AC power cable from the switch panel is 6 ft (1.8 meters) long. It must reach the computer control unit.3. The monitor video cable on most monitors is normally short. Use an extension VGA cable to reach the computer control unit if needed. (Exten-sion cable not supplied).
Fasten the computer control unit in place using the holes in the mounting plate.
2.1.4 Switch PanelThere are two switch panel assemblies, one for a lead screw hoist and the other for a hydraulic hoist. Installation is the same for both. The switch panel does not need to be next to the bulkhead connector.
Switch panels for both the hydraulic hoist and the lead screw hoist are the same size. They provide power to the computer control unit through a 6ft (1.8 meter) cable. This cable must reach the com-puter control unit. Make a hole 2.5 X 2.5 inches (63.5 X 63.5 mm). Pass the wires through the hole and attach the plate by the four corners to the instrument panel. 2.1.5 MonitorSpecifications:1. VGA, 640 X 4802. Horizontal Sync. 31.5 kHz

When selecting a location, keep in mind the fol-lowing:1. Select a location where the monitor is in full view when fishing.2. What voltage is available in the wheelhouse to run the monitor? A converter may be needed to supply the correct voltage.3. If there is a chance the monitor might get wet, install a splash proof or waterproof monitor.4. If the monitor is in direct sunlight, install a sun-light viewable monitor.5. If the monitor will be flush mounted, select a monitor with the on/off and adjustment controls are on the front.6. Most monitors come with cables. The video cable is typically 5 ft (1.5 meters) long. The video cable connects to the computer control unit. If the video cable is not long enough use a standard VGA extension cable.
2.1.6 Audio Line OutputBelow the VGA connector on the computer control unit is a mini jack. This jack will supply the audio line voltage to an external amplifier that is con-nected to the speaker. Speakers with amplifiers are the type used as external speakers on computers. The mini jack on the SS395 is compatible with the computer type speakers.
WARNING: Do not connect speakers directly. In doing so, the audio circuit will be damaged, not covered by warranty. Only use speakers with built in amplifier like the type used on computers.
2.2 Seachest Installation
Checklist: How much room is needed? Seachest location. Seachest Specifications.
17
2.2.1 How much room is needed?There are three measurements needed to determine the vertical height of the hull unit, seachest and hoist assembly together.
1. Depth of keel at the location of the seachest. The overall vertical height is the total length of the seachest plus the hoist assembly on top. If the boat has a keel then part of the seachest will pass through the hull to the bottom of the keel. This distance will reduce the vertical height needed inside the boat. 2. Seachest length. The seachest must be long enough for the soundom to fit inside plus 1 1/2 (38mm) for protec-tion when not in use. This becomes the minimum length. the minimum length is different for the following models:Model: Minimum LengthSS395-E-160 21 in (53.3 cm)SS395-H-160 24 in (61 cm)SS395-E-110 22.5 in (57.2 cm) SS395-H-110 25.5 in (67.8 cm) SS395-E-60 22.5 in (57.2 cm) SS395-H-60 29.5 in (74.9 cm)
3. Hoist length The vertical length is different for the fol-lowing models:Model: Minimum LengthSS395-E-160 25.75 in (65.5 cm)SS395-H-160 33 in (83.8 cm)SS395-E-110 28.75 in (73 cm)SS395-H-110 33 in (83.8 cm)SS395-E-60 28.75 in (73 cm)SS395-H-60 33 in (83.8 cm) 2.2.2 Seachest LocationFor the best sonar performance avoid items in front of the seachest that can create bubbles or turbulence. Items such as zinc plates, cooling pipes, sounder housings, water intakes or discharge ports should NOT be in front of the seachest.
18
Avoid installing the seachest near other sounding equipment. Down sounders should be behind the seachest. Other sonars should be on the opposite side of the keel.
Select a location 1/3 to 1/2 of the ship’s overall length back from the bow. On lighter boats where the bow is likely to come out of the water at times, moving the seachest closer to the half length is recommended.
Athwart Vessel Location: 1. Installation through the keel is optimum, center line of vessel roll. 2. Along side the keel and 1/2 in (13 mm) up from the keel is a very good location, vessel roll is minimal. The keel also adds strength to the seachest as it protrudes through the hull. Fair the seachest to the keel. Alongside the keel will help keep debris from snagging. 3. If next to the keep is impossible, locate the seachest within 40 in (1 meter) from the keel. The bottom of the seachest must extend down to 1/2 in (33mm) up from the keel. Fair the seachest for-and-aft but not to the hull. If faired to the hull, bubbles will travel down the taper to the soundome. To deflect debris a plate cut at a 45 degree angle to the hull should be attached to the leading and trailing edge of the fairing. The plate will deflect debris and not catch on the seachest.
2.2.3 Seachest SpecificationsThe SS395, depending on the model, will have a 6 in soundome or an 8 in soundome. The size of the soundome will determine the pipe and the flange specifications. Use one of the following drawings when fabricating the seachest at the boat yard. Steel and wooden boats use steel. Aluminum boats use aluminum. Fiberglass boats use fiberglass. Fiberglass seachest with flange can be ordered from WESMAR. (6 in part #62.04327.0 or 8 in part #62.04329.0)
6-inch Seachest1. Use 6-inch schedule 80 steel pipe (5.761 Id nominal)2. Length between minimum length (3.2.1) and 40 in (1.2 m)
19
3. Paint inside with same bottom paint as hull.
8-inch seachest1. use 8-inch Schedule 80 steel pipe (7.625 in ID nominal)2. Length between minimum (3.2.1) and 40 in (1.2 m)3. Paint inside with same bottom paint as hull.
2.3 Electrical Hoist Installation
Note: The SS395 can be ordered with an electrical hoist or a hydraulic hoist. Section 3.3 will cover the electrical hoist with 3.6 will cover the hydraulic hoist.
Checlist: Calculate the length of the soundome tube Check soundome clearance inside seachest Fasten the soundome to the soundome tube Assemble hoist Attach hoist to seachest
2.3.1 Calculate Lenth Of Soundome TubeThere are two electrical hoist systems. One for the 6 in soundome and another for the 8 in soundome. The difference between the two is the size of the flange and the total travel.1. 6 in soundome: measure the length of the seachest and add 4 in (10 cm)2. 8 in soundome: measure the length of the seachest and add 5.5 in (14 cm)
When the proper length of the soundome tube is determined, measure from the threaded end, mark the length and cut. File the rough edges.
2.3.2 Check soundome clearance in side seachestThe soundome should not fit tight inside the
20
seachest. This can place addition strain on the hoist motor and damage it. Also, if the insides of the seachest start to rust the dome may jam and possible damage to the hoist motor may be the result. A loose fitting soundome will be subject to vibration reducing sonar performance.
The SS395 soundome must fit the seachest with a clearance no greater than 1/16 in (1.6 mm). Both the 6 in and 8 in ABS soundomes have fins or ribs on the side of the dome. The fins can be filed down for the correct fit.
When checking the soundome, do not handle the soundome by the soundome cable. Hold the dome by the neck.
2.3.3 Fasten the soundome to the soundome tube1. Thread the jam nut into the soundome.
2. Wrap teflon tape around the threads of the soun-dome tube. WARNING: only use Teflon tape on the threads of the soundome tube. Chemical thread sealant will damage the ABS threads of the soundome.
3. Run the soundome cable all the way through the soundome tube, starting from the threaded end. Have a helper hold the soundome at the same time rotate the soundome tube. Be careful not to cross threads. Tighten by hand without tools.
4. Tighten the jam nut using a wrench for a snug fit.
5. To protect the soundome cable from chafing on the end of the soundome tube, a urethane strain relief is supplied. Cut the urethane strain relief down one side. Open the cut and push the soun-dome cable into the strain relief. Slide the strain relief down the cable and into the open end of the soundome tube.
2.3.4 Asemble Hoist1. Remove the packing flax from the packing gland
21
on the flange.
2. Run the soundome cable through the flange following by the soundome tube. Insert the pack-ing flax one at a time. Use a 1/4 in (6 mm) rod to push the flax to the bottom of the packing gland. Rotate the next flax by 90 degrees and push to the bottom. Do the same for the remaining flax, total six pieces. Slide the packing gland cap over the soundome tube. Apply ANTI-SEIZE (supplied) to the thread posts. Thread the two nuts on each cap post DO NOT tighten the 7/16 in nuts.
3. Thread the top hoist clamp onto the lead screw until it is flush with the top.
4. Apply ANTI-SEIZE to the bolts on the saftely clamp and top hoist clamp. Slide the safetly clamp over the soundome tube. DO NOT tighten. Push the soundome tube through the top hoist until 2 in (51 mm) remain on the other side. Tighten the top hoist clamp (3/8 in nuts) so the soundome tube is locked in place.
5. Place safety clamp directly below the top hoist clamp and tighten bolts.
2.3.5 Attach Hoist to Seachest
1. The 6 in soundome has a FWD stamped on top of the dome. Locate this mark and make a new mark on top of the soundome tube in line with the FWD stamp. This mark will be the reference point that points to the bow.
2. The 8 in soundome has an AFT stamped and arrow that points to one of the fins on top of the soundome. Align the AFT fin so it points towards the stern or back of the boat when the soundome goes into the seachest. Make a mark on top of the soundome tube that is in line with the AFT fin on the soundome. This mark will be the reference point that points to the stern of the boat.
3. Clean the flange surface of both hoist and seachest. Place the clean neoprene gasket on the seachest flange. There is no need to grease the gas-
22
ket. Carefully lift the hoist and align the soundome to the opening of the seachest. Lower the hoist onto the seachest. Rotate the hoist for easy access to the TR box. Apply ANTI-SEIZE (supplied) to the 1 inch bolts (supplied). Insert the 1 inch bolt from the bottom up. Use the lock washers and nuts (sup-plied) to tighten the hoist flange to the seachest.
4. Align the soundome to the boat, FWD for the 6 in dome and AFT for the 8 in dome. Loosen the bolts on the top hoist clamp. Rotate the soundome tube so the mark made in step #1 or #2 are in line. Tighten the bolts good and tight.
5. Check the soundome inside the seachest. The hoist is shipped from WESMAR in the up position. The above procedure will place the soundome 1.5 in (38 mm) inside the seachest. If the boat is out of the water, check this distance. To make corrections, loosen the top hoist clamp and push up or down on the soundome tube for the correct measurement. Retighten the hoist clamp.
6. Slide the safety clamp up to the top hoist clamp. Apply ANTI-SEIZE to the bolts and tighten.
2.4 WiringAll the cables are fitted with connectors. They will mate at both ends to the computer control unit in the wheelhouse and to the TR unit located on the hoist assembly.

THIS COMPLETES THE INSTALLATION. REFER TO PART 4, SONAR SYSTEM CHECK, DC HOIST
2.5 Operational Checks 2.5.1 Lowering hoist first time1. Check to make sure there is enough room beneth the boat when the soundome goes down.2. Unplug the hoist motor from the hoist cable.3. In the wheelhouse push the hoist down on the switch panel.4. Plug the hoist motor back into the hoist cable only enough so the motor runs.5. Watch the motor as it travels down. It should stop before the safety clamp comes in contact with the packing gland. If it looks like the safety clamp will hit the packing gland unplug the hoist motor. Rotate the lead screw by hand so the clearance is no less than .5 in (13 mm) above the packing gland. Remove the bronze shear pin at the bottom of the lead screw. Plug the motor back in. The motor will run and stop. Replace the shear pin.6. In the wheelhouse verify the red hoist light is on. This light is a reminder that the hoist is down.7. In the wheelhouse push the hoist switch up to raise the soundome. In about 20 seconds the red hoist lgiht should go out. When the light does go out, check the position of the top hoist clamp. It should be up and the motor has stopped running.
2.5.2 Check hoist travel distanceThe hoist motor is calibrated at the factory for the correct travel distance. Lower the hoist and check

the distance the soundome travels beneath the keel, item #4 below.
To make corrections loosen the top hoist clamp and safety clamp. Move the soundome up or down for the correct position.
2.5.3 Packing GlandTighten the packing gland by rotating the two nuts hand tight then two complete turns with a wrench Tighten the second nut agains the first nut.
When the boat is back in the water, cycle the hoist up and down four times. Check the packing gland for water. It is normal for the packing gland to be wet but not dripping with water. Retighten the nuts on the packing gland. WARNING: Do not tighten the packing gland too tight. A tight packing gland will hold the soundome tube from moving, either the fuse will blow or the bronze shear pin will break.
2.6 Hydraulic Hoist Installation
The hydraulic hoist will require some assembly. There are four parts that make up the complete hoist unit: hoist rack assembly, soundome tube, hydraulic power pack with hydraulic ram and soundome. There are two models of hydraulic pow-er packs, DC and AC. The DC unit can be installed on the hoist rack. The AC, due to its weight, must be installed on a bulkhead. Bulkhead installation may require some longer hydraulic lines.
NOTE: The soundome tube has been cut to match the seachest on board. If there is any uncertainty on the length contact your dealer or WESMAR before proceeding with the in-stallation.
2.6.1 Assemble the soundome tube
1. Remove the packing gland cap and pack flax
26
from inside the packing gland on the flange.
2. Run the soundome tube through the flange and stop when the tube is half way up the rack assembly.
3. Insert the packing flax one at a time. Use a screwdrive to push the flax to the bottom of the packing gland. Rotate the next flax by 90 degrees and push to the bottom. Do the same for the remaining pieces, six in total. Slide the packing gland cap over the soundome tube and down so it is touching the flax. Apply ANTI-SEIZE to the gland cap bolts and thread them in finger tight. Do not tighten at this time.
4. Slide the tube safety clamp over the soundome tube.
5. Slide the tube guide clamp over the soundome tube.
2.6.2 Install the soundome
1. Clean the matting surfaces of the soundome and soundome tube flange.
2. Run the soundome cable through the flange o-ring then through the soundome tube so there is 1 foot 30 cm slack at the dome end.
3. Apply silicone compound to the o-ring. Posi-tion the o- ring in the machined groove on top of the soundome.
4. Use ANTI-SEIZE and bolt the soundome to the soundome tube and tighten.
2.6.3 Install the hydraulic ram
1. Remove the top cross plates from the rack as-sembly. Note which plate is connected to which rack. Make sure the tube guide clamp does not slip off the soundome tube when removing the cross plates.
Safety Clamp
27
2. Remove the cable strain relief from the hydraulic ram end cap.3. Place the soundome cable in the slot on the hydraulic end cap. Slide the hydraulic ram inside the soundome tube. The ram can be disconnected from the hydraulic power pack by using the quick disconnect fittings at the end of the hydraulic lines. Align the soundome cable coming through the end cap with the rack leg that has the limit switches. The cable will be to the left and the limit switches to the right. Push the hydraulic ram in place. Align the holes in the soundome tube with the holes in the ram end cap. Slide the tube guide clamp up over the aligned holes. Bolt all three pieces together. Before tightening visually draw a line from the packing gland bolt and the bolt just installed. Rotate the soundome tube so the two bolts are in line with one another Tigthen the two bolts. Do not tighten the packing gland bolts at this time.4. Place the strain relief grommet around the sound-ome cable. Slide the grommet down the cable until it fits snuggly into the top of the hydraulic end cap. Bolt the strain relief plate over the grommet.5. Push the soundome tube up until the hydraulic ram shaft goes through the holes in the center of the cross plates. Thread the castle nut onto the ram shaft so its snug; at the same time align the holes through the shaft with the nut. Place a cotter pin through the hole and lock it in place.
2.6.4 Install hoist assembly on seachest
Placing the hoist assembly on the seachest will require the assistance of two or three helpers. Use a chainfall connected to the overhead to lift the load.
1. If the hydraulic lines are removed from the ram end cap, the fittings may leak when the hoist is lifted up. To reduce leaking, install the safety clamp around the soundome tube just above the packing cap and tighten inplace. This will keep the soundome tube from slipping down when lifting the hoist.

Alignment considerations: a) Only DC power pack can be installed on the hoist rack. The rack opposite the limited switches is the only rack leg the power pack can be attached to. b) The AC power pack must be installed on a bulkhead. The DC power pack can also be installed on a bulkhead and not on the rack. Rotate the hoist so the rack leg with the limit switches is adjacent to the bulkhead that has the power pack. This will avoid crossing the hydraulic lines.
4. Bolt the hoist flange to the seachest. Apply ANTI-SEIZE on the bolt threads. Insert the bolts from the bottom up. Use the lock washer and nuts and tighten in place.
5. Tighten the packing gland cap bolts finger tight. Use wrench and tighten each bolt one full turn, repeat for a total of two turns. NOTE: When the vessel is back in the water, cycle the hoist up and down four times. Check the pack-ing gland for water. It is normal for the packing gland to weep but not drip. Tighten if necessary. 2.6.5 Install hydraulic power pack
1. Install the DC power pack on the rack leg op-posite the leg with the limit switches. About half way up on the leg are two holes where the DC mounting bracket will bolt to. Use ANTI-SEIZE and tighten in place. Connect the hydraulic lines to the cylinder.
2. Install the AC power pack to the bulkhead. Use the mounting bracket attached to the motor. Gener-ally taped standoffs are welded to the bulkhead and the motor will bolt to them. The hydraulic lines will
2. Clean the flange surfaces of the seachest and hoist. Place the neoprene gasket on the seachest flange.
3. Lift the hoist assembly and set it on top of the seachest. Rotate the flange to coincide with the hoist power pack and limit switches for easy maintenance.

need to be lengthened. Make sure there is enough slack in the lines for up and down travel. Connect the hydraulic lines to the cylinder.
3. After the hydraulic lines are connected make sure they are free to travel and no change to catch on nonmoving part. The soundome cable must also be free to travel and not catch on any nomoving part.
4. Install the vent screw in the reservoir. In order to ship the hydraulic power pack full of oil the vent screw was replaced with non-venting screw. This non-venting screw must be removed and replaced with the supplied venting tape.
2.7 Wiring, DC Hydraulic Hoist
The DC hydraulic hoist is a stand alone sys-tem that does not require power from the sonar. It will operate on its own. The hydraulic power pack is avialable in 12V, DC and 24V DC. Wiring is dif-ferent between the two voltage systems. Check the voltage of the hydraulic pack unit before wiring.
2.7.1 DC hoist board wiring
1. The DC hoist board is enclosed in its own alumi-num box. The DC hoist board will work on both 12V hydraulic power pack units and 24V hydraulic power pack units.
2. Hoist control cable, PN: 78.10015.0The hoist control cable is 25 feet (7.6 meters) long. One end is terminated witha six pin connector, the other end is terminated with terminal lugs. The connector end will mate with the connector on the switch panel in the wheelhouse. the other end will go through a strain relief fitting on the hoist control box and connect to termintal TB1, number to number.If a longer hoist control cable is needed, hoist ex-tension cables are avialable in 25 feet (7.6 meter)

3. Hoist board voltageVoltage to the hoist board must be the same as the voltage for the hydraulic power pack. This voltage powers the solenoid valve, the big relay on the DC motor, the up/down relays on the hoist board and the red and green lights on the switch panel in the wheelhouse. The hoist board is fused with a 5A slow blow fuse. Run ships power through a strain relief fitting on the hoist box and connect the battery negative to terminal #31 and battery positive to terminal #30. Use the correct wire size to carry 5 amps over the distance from battery to hoist board.
4. Solenoid valve wiringThe large relay on the DC motor is activated by the same voltage that operates the solenoid valve. To simplify wiring the relay is pre-wired into the solenoid valve. From the solenoid valve there is a pre-wired cable with numbered lugs at the end. Pass the cable through a strain relief on the bot-tom of the hoist box. Connect the wires to TB2, number to number.
5. Limit switch up/down wiringLocated on the hoists are two limit switches that will stop the hoist at its up and down limits. Both switches are pre-wired and numbered at WES-MAR. Run the limit switch wires through a strain relief on the hoist box. Connect the wires to TB2, number to number.
6. DC motor wiringThe hydraulic power pack is available in 12V and 24V. Confirm the voltage of your unit before wiring. The 12V motor will draw 65 amps under normal load. The 24 volt motor will draw 40 amps under normal load. The amperage will go up if resistance in hoisting increases. Fuse the 12 volt motor for 130 to 140 amps. Fuse the 24 volts for 55 to 60 amps. Select a wire guage appropriate for the load. The hoist takes less than ten seconds to go up or down so the cycle is very short before it turns off. Wire as pictured to the left.

2.8 Wiring, AC hydraulic hoist
The AC wiring hoist is a stand-alone sys-tem that does not require power from the sonar to operate. It will operate independent from the sonar. The hydraulic power pack is available 110V AC signle phase and 220V AC single phase. Wiring is the same for both systems.
2.8.1 AC hoist board wiring
1. The AC hoist board is enclosed in its own alu-minum box. Before wiring, check the AC voltage of the board. Next to transoformer T1 there will be one or two jumpers installed. One jumper is for 220V AC and two jumpers are for the 110V AC NOTE: Use a 30 amp slow blow fuse for 110V AC and a 20 amp slow blow fuse for 220V AC.
2. Hoist board voltage. Voltage to the hoist board is the same voltage that will power the motor and the solenoid valve on the hydraulic power pack. Run ships AC power through one of the strain relief fittings on the hoist box and connect the wires to TB3. Use wire size capable to handle a one horsepower motor.
3. Hoist control cable, PN: 78.10015.0The hoist cable is 25 feet (7.6 meters) long. One end is terminated with a six pin connector, the other end is terminated with terminal lugs. The connector will mate with the connector on the switch panel in the wheelhouse. The other end will go through one of the small strain relief fittings on the hoist control box. Connect each number wire to the same numbered terminal on TB1.If longer hoist control cable is needed, hoist exten-sion cables are available in 25 feet (7.6 meters) in length, PN: 78.10015.1.
4. Solenoid valve wiring
32
The solenoid valve is pre-wired with terminal lugs at the ends. Run the solenoid cable through one of the strain relief fittings on the hoist box. Connec the wires to TB2, number to number.
5. Limit switch up/down wiring:There are two limit switches on the hoist rack that will stop the hoist at the travel limits. Both swtiches are pre-wired with terminal lugs at the ends. Run the limit switch wires through on of the strain relief fittings on the hoist box. Connect the wires to TB4, number to number.
2.9 Operation check, hydraulic hoist, DC & AC
2.9.1 Lowering hoist first time
1. Check to make sure there is enough room be-neath the boat before lowering the soundome. Total travel is 18 inches, 45.5cm. Outside the seachest 16.5 inches, 42cm.
2. Make sure the hoist switch is in the up posi-tion.
3. Disconnect the upper hoist limit switch wire labeled #27 located on, TB2 for DC motors or TB4 for AC motors. Once this wire is disconnected the hoist will only move down when powered.
4. Disconnect the hoist down limit switch wire la-beled #1 located on, TB1 for DC motors and TB1 for AC motors. Once this wire is disconnected the hoist will not move when the hoist switch in the wheelhouse is pushed down to lower the soundome.
5. 1. The hoist will lower. The hoist should stop before the safty clamp comes in contact with the packing gland. If it looks like the safety clamp will come in contact with the packing gland remove the wire immediately. Tap the wire on terminal #1 for short movements until the hoist stops. The top clamp should stop no less then 0.5 inches, 13mm
33
above the packing gland.
Adjustment - Move the lower limit switch up on the hoist rack so the top clamp is 0.5 inch, 13mm to 1.0 inch, 25.5mm above the packing gland6. Lift up the soundome - Push the hoist switch up in the wheelhouse. Touch the wire labeled #27 to terminal #27. The hoist will start to go up. The hoist should go up and stop and the motor turn off.
Adjustment - If the motor keeps running when the hoist has stopped in the up position the top limit switch must be lowered. Lower the limit switch so the hoist will stop 0.5 inch, 13mm before the mechanical stop. 7. Connect the wires back to terminal #27 and #1.
2.9.2 Check hoist soundome travel.
1. Lower the soundome, push the hoist switch down in the wheelhouse.
2. Measure the distance from the bottom of the seachest to the bottom of the soundome under the boat. The distance should be 16.5 inch, 42mm to 15.5 inch, 39mm.
2.9.3 Packing gland
1. Tighten the packing gland by rotating the two nuts hand tight then two complete turns with a wrench. Tighten the second nut against the first nut to lock.
2. When the boat is back in the water cycle the hoist up and down four times. Check the packing gland for water. It is normal for the packing gland to be wet but not dripping with water.
3. Retighten the nuts if water drips after cycling the hoist. WARNING: Do not tighten the packing gland too tight. A tight packing gland will hold the soundome tube from moving and may trip the
34
circuit breaker or damage to the electric motor.
4. From time to time inspect the packing gland. Tighten if needed.
2.10 Hydraulic Hoist Trou-bleshooting
1. Up and down are reversed: a. Solenoid valve is wire opposite. b. Hydraulic lines are reversed.2. Hoist motor runs, green light on, but will not raise or lower. a. Solenoid valve stuck. b. Check solenoid wiring. c. Fluid level in reservoir is too low. d. Packing gland cap is too tight. e. Hoist rack is bent. f. Obstruction in seachest. g. Reservoir is not vented.
3. Hoist motor continues to run, green light on, hoist did go up & down. a. Limit switch arm not triggering. b. Soundome tube not traveling all the way. c. Broken wires to limit switches. d.Reservoir low on fluid.
4. Soundome tube will not stay up. a. Dirty check valve. b. Leak in hydraulic lines. c. Leak in hydraulic cylinder.
35
2.11 Hydraulic Maintenance
Monthly checks:1. Oil Reservoir - Fluid level should be at the venting plug with the hoist in the up position. Oil, Chevron automatic transmission fluid, “Dexron II” or equivalent.2. Packing gland - Little water should weep from the packing. It should not drip. If there is too much water coming from the packing gland tighten each of the cap bolts one full turn. Run the hoist up and down and check for water. If the packing gland cap has bottomed out, add one new layer of packing, Wesmar part #09.00749.03. Check all wiring and hydraulic lines that may catch or snag when the hoist is moving
