FLUSHING COOLING SYSTEM - SEA-WATER
SECTION
To prevent silt and/or salt build-up in the cooling system
(fresh or raw-water cooled), fl ush the sea-water section
of the cooling system with fresh water at specifi ed
intervals. Close seacock (if applicable) before removing
inlet hose.
CAUTION
Do not operate the engine without suffi cient amount
of water being supplied to the sea-water pump.
The sea-water pump impeller may be damaged and
subsequent overheating damage may result.
CAUTION

fl ushing. Suction created by the sea-water pump
may collapse the fl ushing hose, causing the engine
to overheat. Watch the temperature gauge while
fl ushing to ensure the engine does not overheat.
