8. Sea Water Filter (Optional)
When operating the engine in areas where the sea water
contains a large amount of mud, sand or other foreign
matter, a sea water filter should be provided between the
kingston cock and the sea water pump.
Occasionally inspect the sea water filter and clean the dirt
and scale off the element. Remove the dirt and sand from
the bottom of the filter.
