If the outboard motor is installed toolow, the boat will squat and be hardto plane, it will tend to porpoise, andhigh-speed stability will be reduced.

If the outboard motor is installed toohigh, that will cause ventilation.

Optimum installation height varieswith boat type and bottom shape.Contact the boat manufacturer forany special recommendations that areunique to a specific model of boat.

If the transom needs to be modifiedto accommodate the outboard motor,contact the boat manufacturer andfollow their recommendations forcorrective action.

Attach the stern bracket to the boattransom by tightening the clampscrews.

Attach a rope from the boat to thehole in the stern bracket. This willhelp to prevent accidental loss of theoutboard motor.

You may further secure the outboardmotor by bolting the stern bracket tothe boat transom. Use the optionalmounting bolt and nut kit or othergood quality stainless steel bolts, nuts,and washers. Apply silicone sealantto the bolt holes.

IMPORTANT SAFETYINFORMATION

BEFORE OPERATION.

To safely realize the full potential ofthis outboard motor, you need acomplete understanding of itsoperation and a certain amount ofpractice with its controls.

Before operating the outboard motorfor the first time, please review the

on page and thechapter titled

For your safety, avoid starting oroperating the engine in an enclosedarea. Your engine’s exhaust containspoisonous carbon monoxide gaswhich can collect rapidly in anenclosed area and cause illness ordeath.

Proper break-in operation allows themoving parts to wear in smoothly forbest performance and long servicelife.

Run the engine at trolling speed. Usethe minimum throttle openingnecessary to operate the boat at a safetrolling speed.

Run the engine up to a maximum of2,000 to 3,000 rpm, which is about10% to 30% of maximum throttleopening.

Run the engine up to a maximum of4,000 to 5,000 rpm, which is about50% to 80% of maximum throttleopening.

Short full-throttle bursts are OK, butdo not operate the enginecontinuously at full throttle.

For boats that plane easily, bring theboat up on plane, and then reduce thethrottle opening to the recommendedrpm range.

Do not run the engine at full throttlefor more than 5 minutes at a time.

For rough water conditions or largewaves, slow down to prevent thepropeller from rising out of the water.

Under normal conditions, the boatwill perform best when theantiventilation plate is level with thewater.

Install the outboard motor at the besttransom angle for stable cruising andmaximum power.

Transom angle too large: Incorrectcauses boat to ‘‘squat’’.

Transom angle too small: Incorrectcauses boat to ‘‘bow steer’’.

It is necessary to adjust the transomangle of the outboard motor tocompensate for changes in boat load,weight distribution, water conditions,or propeller selection.

When cruising into a high wind,adjust the outboard motor downslightly to level the boat and improvestability. With a tail wind, adjust theoutboard motor up slightly (p. ).

THE IMPORTANCE OFMAINTENANCE

Maintenance, replacement, orrepair of the emission controldevices and systems may beperformed by any marine enginerepair establishment or individual,using parts that are ‘‘certified’’ toEPA standards.

SERVICING YOUR OUTBOARD MOTOR

Good maintenance is essential forsafe, economical, and trouble-freeoperation. It will also help reduce airpollution.

To help you properly care for youroutboard motor, the following pagesinclude a maintenance schedule,routine inspection procedures, andsimple maintenance procedures usingbasic hand tools. Other service tasksthat are more difficult, or requirespecial tools, are best handled byprofessionals and are normallyperformed by a Honda technician orother qualified mechanic.

Remember that your authorizedHonda marine dealer knows youroutboard motor best and is fullyequipped to maintain and repair it.

To ensure the best quality andreliability, use only new, genuineHonda parts or their equivalents forrepair and replacement.

The maintenance schedule applies tonormal operating conditions. If youoperate your outboard motor underunusual conditions, consult anauthorized Honda marine dealer forrecommendations applicable to yourindividual needs and use.

Honda will not deny a claim forwarranty coverage simply becauseyou did not maintain your outboard.However, any part that fails due tolack of maintenance, or impropermaintenance will not be coveredunder your product warranty.

MAINTENANCE SAFETY Safety Precautions

Burns from hot parts.

Injury from moving parts.

Carbon monoxide poisoningfrom engine exhaust.


Some of the most important safetyprecautions follow. However, wecannot warn you of everyconceivable hazard that can arise inperforming maintenance. Only youcan decide whether or not you shouldperform a given task.

Make sure the engine is off beforeyou begin any maintenance orrepairs. This will eliminate severalpotential hazards:

Read the instructions before youbegin, and make sure you have thetools and skills required.

To reduce the possibility of fire orexplosion, be careful whenworking around gasoline. Use onlya nonflammable solvent, notgasoline, to clean parts. Keepcigarettes, sparks, and flames awayfrom all fuel-related parts.

Wear gloves when handling thepropeller to protect your handsfrom sharp edges.Let the engine and exhaust

system cool before touching.

Do not run the engine unlessinstructed to do so.

Be sure there is adequateventilation whenever youoperate the engine.

Use unleaded gasoline with a pumpoctane rating of 86 or higher.


Running the engine with persistentspark knock or pinging can causeengine damage.

Distributor’s LimitedWarranty

Your outboard motor is certified tooperate on unleaded gasoline.Unleaded gasoline produces fewerengine and spark plug deposits andextends exhaust system life.

Never use stale or contaminatedgasoline or an oil/gasoline mixture.Avoid getting dirt or water in the fueltank.

Occasionally you may hear a light‘‘spark knock’’ or ‘‘pinging’’(metallic rapping noise) whileoperating under heavy loads. This isno cause for concern.

If spark knock or pinging occurs at asteady engine speed, under normalload, change brands of gasoline. Ifspark knock or pinging persists, seean authorized Honda marine dealer.

Running the engine with persistentspark knock or pinging is misuse,and the

does not cover partsdamaged by misuse.

The fuel pump filter is located underthe engine cover, on the right side ofthe engine.

Water or sediment accumulated inthe filter can cause loss of power orhard starting. To prevent enginemalfunction, inspect the filter andreplace when necessary.

Adding a Fuel StabilizerDraining the Fuel System

Distributor’s Limited Warranty

Gasoline will oxidize and deterioratein storage. Old gasoline will causehard starting, and it leaves gumdeposits that clog the fuel system. Ifthe gasoline in your fuel tank andcarburetor deteriorates during storage,you may need to have the carburetorand other fuel system componentsserviced or replaced.

The length of time that gasoline canbe left in your fuel tank andcarburetor without causing functionalproblems will vary with such factorsas gasoline blend, your storagetemperatures, and whether the fueltank is partially or completely filled.The air in a partially filled fuel tankpromotes fuel deterioration. Verywarm storage temperatures acceleratefuel deterioration. Fuel deteriorationproblems may occur within a fewmonths, or even less if the gasolinewas not fresh when you filled thefuel tank.

Thedoes not cover fuel system damageor engine performance problemsresulting from neglected storagepreparation.

You can extend fuel storage life byadding a gasoline stabilizer that isformulated for that purpose, or youcan avoid fuel deterioration problemsby draining all the fuel from the fueltank and carburetor.

When adding a fuel stabilizer, fill thefuel tank with fresh gasoline. If onlypartially filled, air in the tank willpromote fuel deterioration duringstorage. If you keep an additionalcontainer of gasoline for refueling,be sure that it contains only freshgasoline.

Add fuel stabilizer following themanufacturer’s instructions.

After adding a fuel stabilizer, runthe engine in water for 10 minutesto be sure that the treated gasolinehas replaced the untreated gasolinein the carburetor.

Turn the engine OFF.

You can avoid fuel deteriorationproblems by draining the fuel tankand carburetors.

STORAGE

Drain the portable fuel tank into anapproved gasoline container, or ifyou need to store fuel in the fueltank, you can extend fuel storagelife by filling the fuel tank withfresh gasoline and adding a fuelstabilizer that is formulated forthat purpose. Firmly close the fuelcap vent knob.

After the fuel has drained from thecarburetor, tighten the drain screwsecurely.

With the outboard motor in avertical position, place anapproved gasoline container belowthe fuel drain outlet, and use afunnel to avoid spilling fuel.Loosen the drain screw to drainfuel from the carburetor.

Store portable fuel tank in a coolplace.

(remote control type)

If the throttle is closed suddenly afterfull throttle operation, engine speedmay drop below the specified idlerpm, and that could activate theengine protection systemmomentarily.

If low oil pressure activates theengine protection system, stop theengine, check the engine oil level(p. ), and add oil if needed.

With the engine oil at therecommended level, restart theengine. If the lubrication system isOK, the green indicator light shouldcome on within 30 seconds, and theengine will respond normally tothrottle grip or control leveroperation.

If the engine protection systemremains activated after 30 seconds,return to the nearest boat landing,and have the outboard motorinspected by an authorized Hondamarine dealer.

If oil pressure becomes low, thegreen indicator light will go off, andthe engine protection system willlimit engine speed. If you are atcruising speed, engine speed willdecrease automatically.

When normal oil pressure is restored,the engine speed will gradually riseto normal engine speed.

Remote-control types are equippedwith a buzzer that sounds when thegreen indicator light goes off.The buzzer sound stops below anengine speed of 1,400 rpm.

Low oil pressure may be the result ofa low engine oil level, or there maybe a problem with the enginelubrication system.

SUBMERGED MOTOR


RECOIL STARTER GRIP

A submerged outboard motor mustbe serviced immediately after it isrecovered from the water in order tominimize corrosion.

If the engine was running when itsubmerged, there may bemechanical damage, such as bentconnecting rods. If the enginebinds when cranked, do notattempt to run the engine until ithas been repaired.

Change the engine oil and oil filteras described on p. . Ifthere was water in the enginecrankcase, or if the used engine oilshowed signs of watercontamination, then a secondengine oil change should beperformed after running the enginefor half an hour.

Remove the engine cover, andrinse the outboard motor withfresh water to remove salt water,sand, mud, etc.

Remove the spark plugs (p. ),and remove the clip from theemergency stop or engine switch.Pull the recoil starter grip, rotatethe flywheel a few revolutions tocompletely expel any water fromthe cylinders.Drain the carburetor as described

Carburetor Modification forHigh Altitude Operation


When the carburetors have beenmodif ied f or high altitude operation,the air-f uel mixture will be too leanf or low altitude use. Operation ataltitudes below 5,000 f eet (1,500meters) with modif ied carburetorsmay cause the engine to overheatand result in serious engine damage.For use at low altitudes, have anauthorized Honda Marine dealerreturn the carburetors to originalf actory specif ications.

At high altitude, the standardcarburetor air-fuel mixture will betoo rich. Performance will decrease,and fuel consumption will increase.A very rich mixture will also foul thespark plugs and cause hard starting.

High altitude performance can beimproved by specific modificationsto the carburetors. If you alwaysoperate your outboard motor ataltitudes above 5,000 feet (1,500meters), have an authorized Hondamarine dealer perform this carburetormodification.

Even with carburetor modification,engine horsepower will decreaseabout 3.5% for each 1,000-foot (300-meter) increase in altitude. The effectof altitude on horsepower will begreater than this if no carburetormodification is made.

Oxygenated Fuels

ETHANOL:

MTBE:

METHANOL:


Some conventional gasolines arebeing blended with alcohol or anether compound. These gasolines arecollectively referred to as oxygenatedfuels. To meet clean air standards,some areas of the United States andCanada use oxygenated fuels to helpreduce emissions.

If you use an oxygenated fuel, besure it is unleaded and meets theminimum octane rating requirement.

Before using an oxygenated fuel, tryto confirm the fuel’s contents. Somestates/provinces require thisinformation to be posted on the pump.

The following are the EPA-approvedpercentages of oxygenates:

ethyl or grain alcohol;10% by volume.

You may use gasoline containing upto 10% ethanol by volume. Gasolinecontaining ethanol may be marketedunder the name ‘‘Gasohol’’.

Methyl Tertiary Butyl Ether;15% by volume.

You may use gasoline containing upto 15% MTBE by volume.

methyl or woodalcohol; 5% by volume.

You may use gasoline containing upto 5% methanol by volume, as longas it also contains cosolvents andcorrosion inhibitors to protect thefuel system. Gasoline containingmore than 5% methanol by volumemay cause starting and/orperformance problems. It may also

damage metal, rubber, and plasticparts of your fuel system.

If you notice any undesirableoperating symptoms, try anotherservice station, or switch to anotherbrand of gasoline.

Fuel system damage or performanceproblems resulting from the use of anoxygenated fuel containing morethan the percentages of oxygenatesmentioned above are not coveredunder warranty.

Emission Control SystemInformation


Source of Emissions

Tampering and AlteringThe U.S. and Calif ornia CleanAir Acts

The combustion process producescarbon monoxide, oxides of nitrogen,and hydrocarbons. Control ofhydrocarbons and oxides of nitrogenis very important because, undercertain conditions, they react to formphotochemical smog when subjectedto sunlight. Carbon monoxide doesnot react in the same way, but it istoxic.

Honda utilizes lean carburetorsettings and other systems to reducethe emissions of carbon monoxide,oxides of nitrogen, and hydrocarbons.

Tampering with or altering theemission control system may increaseemissions beyond the legal limit.Among those acts that constitutetampering are:

Removal or alteration of any partof the intake, fuel, or exhaustsystems.

Alterations that would cause theengine to operate outside its designparameters.

The following instructions andprocedures must be followed in orderto keep the emissions from yourHonda engine within the emissionstandards.

EPA and California regulationsrequire all manufacturers to furnishwritten instructions describing theoperation and maintenance ofemission control systems.

A manufacturer of an aftermarketpart assumes the responsibility thatthe part will not adversely affectemission performance. Themanufacturer or rebuilder of the partmust certify that use of the part willnot result in a failure of the engine tocomply with emission regulations.

Follow the maintenance schedule onp. . Remember that this scheduleis based on the assumption that yourmachine will be used for its designedpurpose. Sustained high-loadoperation, or use in unusualconditions, will require morefrequent service.

If you are aware of any of thefollowing symptoms, have yourengine inspected and repaired byyour servicing dealer.

Hard starting or stalling afterstarting.

Rough idle.

Misfiring or backfiring under load.

Afterburning (backfiring).

Black exhaust smoke or high fuelconsumption.
