seawater pump;
no belts to replace.
(2) Easy to clean,

(4) Bronze
and stainless
steel seawater piping.
• Cupro-nickel transmission oil cooler (5)
uses thermostatically controlled engine
coolant for constant gear temperature to
prevent condensation.
• Zinc anodes for electrolysis protection.
Lubrication System
• (1) Spin-on oil filter has a full fl ow and a
bypass element to trap both small and large
contaminates and water.
• (2) Plate-type, full flow
oil cooler uses engine
coolant to reduce oil
t e m p e r a t u r e a n d
thermal breakdown.
• 500 hour oil change
when using specifi ed
oil and fuel.
• Multiple oil fill and
dip stick locations
provide either side service access.
• Positive displacement gear-type oil pump.
• Oil spray cooling reduces piston crown
temperature for longer life.
• Large capacity oil pan.
Air System
• US EPA Tier II and IMO exhaust emissions
compliant.
• Turbocharged and aftercooled for increased
power and performance.
• Turbocharger turbine housing (1) is jacket
water cooled for safety.
• Dry air filter (2)
protects engine

• Two pass, jacket water cooled, charge
air aftercooler. Using thermostatically
controlled jacket-water instead of seawater
normalizes combustion air temperatures
to avoid over cooling under light load
conditions.
ESP and DC Electrical System
• 24 volt, standard
ground electrical
system with 24-volt

(1) and starter.
• Eight groove poly-

• Auxiliary Drives:
Gear driven, SAE

A, 9 tooth spline
auxiliary drive (1)
provides up to 75 foot
lbs of torque to run
hydraulic pumps. On
keel cooled engines
only, an additional gear driven, SAE B, 13
tooth spline, auxiliary drive (2) provides
up to 131 foot lbs of torque. Note: if both
drives are used the maximum combined
total torque available is 131 ft lbs.
