FLUSHING COOLING SYSTEM - SEA-WATER
SECTION
To prevent silt and/or salt build-up in the cooling system
(fresh or raw-water cooled), flush the sea-water section
of the cooling system with fresh water at specified
intervals. Close seacock (if applicable) before removing
inlet hose.
CAUTION
Do not operate the engine without sufficient 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
Do not run the engine above 1500 RPM when
flushing. Suction created by the sea-water pump
may collapse the flushing hose, causing the engine
to overheat. Watch the temperature gauge while
flushing to ensure the engine does not overheat.
WARNING
Do not remove cooling system filler cap when the
engine is hot. Allow the engine to cool and then
remove the pressure cap slowly, allowing the
pressure to vent. Hot coolant, under pressure, may
discharge violently and cause severe burns.
1. Obtain red litmus paper from a local supplier
(drugstore, laboratory, etc.).
2. Remove the pressure cap from the coolant degas
bottle and insert one end of the litmus paper into
the coolant.
3. If red litmus paper turns blue, coolant is alkaline
and does not need to be replaced. If the litmus
paper remains red, the coolant is not alkaline and
must be replaced.

this manual for proper locations.
Remove the following drain plugs/hoses in order to drain
the coolant from the fresh-water portion of the cooling
system.

A. Drain plug from heat exchanger.
B. Remove large hose from the engine block water
circulating pump.
C. Drain plugs from each side of the cylinder block.
NOTE: After the system has drained completely, coat
drain plugs with PerfectSeal (or equivalent) and reinstall
in proper locations. Reinstall hose(s) and tighten clamps
securely as required.
