Sea Water Pump (008-057)
General Information
NOTE: Most sea water systems for heat exchanger-cooled
engines use a sea water strainer. The strainer removes
debris from the sea water before it enters the sea water
pump.
Typical sea water strainer arrangement.
Inspect the sea water strainer daily for any foreign objects
that can restrict water flow.
CAUTION
A restricted or clogged sea water strainer can result in
hotter than normal, or overheated, engine coolant and
marine gear oil temperatures.
For more detailed information, refer to Sea Water Strainer
Cleaning in this section.
NOTE: If the sea water strainer is below water level, close
the sea water inlet valves before servicing the sea water
strainer.
