Raw Water System
You should refer to the air conditioner owner’s
manual for more information on the operation and
maintenance of the seawater pump.
8.5 Generator Raw Water Supply
The generator engine uses a closed cooling sys-
tem with a seawater-cooled heat exchanger. The
seawater circulates through the heat exchanger
and is expelled through the generator exhaust sys-
tem, cooling it as well. It includes a strainer that
prevents debris in the seawater from entering the
cooling pump. The strainer is located in the stern
bilge and supplied seawater by a dedicated thru-
hull fitting and seacock valve near the strainer.
It is important to check and clean the strainer
regularly to ensure the seawater system can cir-
culate 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.
8.6 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 or replace deteriorated hoses and
components as necessary.
• Periodically remove and clean the water
strainer located near the intake side of the
raw water pump. To clean the strainer, make
sure the Raw Water switch is off and close
the valve at the thru-hull fitting. 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 fishbox and baitwell should be drained and
cleaned after each use.
• Operate all valves at least once a month to
keep them operating properly.

CAUTION
SHOULD A HOSE RUPTURE, TURN THE PUMP OFF IMMEDIATELY.
ALWAYS CLOSE THE THRU-HULL VALVE WHEN PERFORMING
MAINTENANCE ON A SEAWATER PUMP.
THE BATTERIES MUST BE PROPERLY CHARGED. OPERATING
ANY PUMPS FROM A BATTERY WITH A LOW CHARGE MAY LEAD
TO A PUMP FAILURE.
THE RAW WATER SYSTEM MUST BE PROPERLY WINTERIZED
PRIOR TO WINTER LAY-UP. SEE SECTION ON WINTERIZING.
Cleaning the Generator Sea Strainer
• Turn off the generator.
• Close the generator intake water seacock.
• Turn the strainer bowl counterclockwise to
remove it and remove the screen.
• Thoroughly flush the screen and the inside of
the strainer bowl to remove foreign matter.
