I have the original (1979) Volvo Penta MD11C on my boat, it always has
lived in salt water. I have a small strainer mounted about one foot above
the
water line. The basket is about 2-1/2" dia. and about 6" tall, which seems
to
be sufficient. I know there are divided opinions about the mounting height,
some people prefer it just below the water line to avoid having to prime it
occasionally and also giving the impeller a little more head pressure,
others
worry about a potential leak draining into the boat. I have lost prime in
the past due to a minute air leak in the top gasket of the strainer, so I
keep
a wary eye on the temp. gauge, since it only takes about three minutes to
overheat the engine. Sailing mostly singlehanded myself I like having access
to the filter inside the boat.
