VOLVO PENTA ADVANCED PROPULSION SYSTEM
TAMD63/K25/K28Complete optimized waterjet propulsion system
based on 6-cylinder, 4-stroke
direct-injected turbocharged aftercooled marine diesel engine
with Kamewa mixed fl ow waterjet – crankshaft power* 234–272 kW
(318–370 hp)
* Power rating – see Technical Data
True Waterjet PerformanceVolvo Penta, in co-operation with
Kamewa, has further developed the use of waterjets as an integrated
part of a complete pro- pul sion system. This comprises the Volvo
Penta waterjet adapted diesel engine, matched marine gearbox, fl
exible but tor- sion stiff coupling and shafting, the high effi
ciency Kamewa mixed fl ow waterjet and a waterjet/engine control
system.
Marine gearbox as standardTo obtain good overall performance,
good fuel economy and good thrust over the whole speed range, the
Volvo Penta die sel engine and the Kamewa waterjet are correctly
matched to each other at op- ti mum impeller speed. Each
combination of engine and jet has an optimized gear ratio as part
of the standard Volvo Penta ad vanced propulsion system. Other im-
por tant benefi ts with the marine gearbox are the possibility to
disengage the jet unit when starting or idling and to backfl ush if
necessary to rinse the jet unit.
Excellent maneuverabilityThe system gives excellent ma neu ver
-abil i ty in all kinds of sea and weather con di tions. Superior
control of the boat is achieved across the complete speed range,
with small turning ra di us and quick stops. With the in te grat ed
ma- neu ver ing system the boat can ro tate within its own length,
and with two wa- ter jets the boat can move side ways.
Easy installationA very compact and easy installation can be
achieved thanks to the drop cen ter marine gearbox and a drive
shaft which is parallel to the baseline of the boat. A com plete
and carefully matched pro pul sion system from a sin gle source
gives a number of ad di -tion al benefi ts:– All parts matched to
each other– Reduced installation time– Easy commissioning of the
boat
Long service lifeThe correctly sized and matched waterjet gives
very small torque variations and elim i nates engine overload,
regardless of the boat’s loading conditions and speed. The waterjet
shaft is always rotating in one di rec tion; the reversing of the
boat is done by changing the jet stream direction with a split
reverse bucket, without giving any sig- nifi cant load variations
on the engine.
Safe and effi cient operationThe Volvo Penta advanced propulsion
system offers many benefi ts, including minimizing the draught. No
underwater appendages reduce the drag of the hull and the risk of
personal injury during res cue or diving operations. In addition,
the inboard noise and vibration and the hydroaccoustic noise are
kept on a low level with the Kamewa mixed fl ow wa ter jet.
The system shown may vary from the standard unit.

TAMD63/K25/K28Technical DescriptionComplete SystemThe Volvo
Penta Advanced Propulsion Sys tem TAMD63L/K28 and TAMD63P/K25 or
K28 are optimized com plete wa ter jet pro- pul sion sys tems based
on the Volvo Pen ta TAMD63 die sel en gine, Ka me wa K25 and Kamewa
K28 mixed fl ow waterjet. The sys tem com pris es a marine gearbox
ZF 220-EB and a CV shaft type CV42 as stan dard. The systems are
designed for speed up to 50 knots and are suitable for single, twin
or multi installations. For each ap pli ca tion Volvo Penta
produces accurate thrust curves for the complete system based on
the nominal service speed of the vessel. The engine and the wa ter
jet are matched to each other in the standard system with an
optimum gear ratio. Kamewa mixed fl ow waterjet with a fl ush in
take parallel to shaft line and with a tran som plate mounted 90°
to bottom plate. The shaft line is designed to be parallel with the
base line of the boat with the drive shaft placed approx. 50 mm (2
in.) below design water line to ensure safe priming. The waterjet
is cou pled to the en gine with a fl exible but torsion stiff shaft
cou- pling and a marine gearbox with drop center.
