Raw Water System
8.7 Generator Raw Water Supply
The generator engine uses a closed cooling system
with a seawater cooled heat exchanger. Seawa-
ter circulates through the heat exchanger and is
expelled through the generator exhaust system,
cooling it as well. It includes a strainer that pre-
vents debris in the seawater from entering the
cooling pump. The strainer is located in the aft
systems compartment bilge near the generator
and supplied seawater by a dedicated thru-hull
fitting and seacock valve near the strainer. It is
important to check and clean the strainer regu-
larly to ensure the seawater system can circulate
enough water to cool the heat exchanger and
exhaust system on the generator. Refer to Raw
Water System Maintenance in this chapter for
information on cleaning the sea strainer.
You should also read the generator owner’s man-
ual for detailed information on the safe operation
and maintenance of the generator.
8.8 Raw Water System Maintenance
The following items should be done routinely to
help maintain your raw water system:
Routine Maintenance
•
Check hoses, particularly the seawater supply
lines, for signs of deterioration. Tighten
fittings and clamps or replace deteriorated
hoses and components as necessary.
•
Periodically remove and clean the water
strainer located near the intake side of the
washdown pump. To clean the strainer, make
sure the Raw Water switch is off and close
the valve at the raw water manifold. Rotate
the strainer bowl counterclockwise to release
it. Remove and clean the screen with fresh
water. Lubricate the O-ring lightly with silicon
or Teflon grease and reinstall the strainer bowl.
•
Spray pumps and thru-hull valves with a pro-
tective oil periodically.
• The fishboxes and baitwells should be drained
and cleaned after each use.
•
Operate all valves at least once a month to
keep them operating properly.
