TP-5695 12/936-8 Installation
A seawater strainer of sufficient capacity should be
mounted to the seacock or permanent structure at a
point not higher than the seawater pump. The strainer
shouldbeaccessibleforservicing.SeeFigure 6-13fora
typical installation. The optional Kohler seawater
strainer is threaded for 1/2 NPT fittings.

NOTE
Some seawater strainers include seacock and intake
thru-hull strainer.
Waterlines from the seacock to the engine-driven
seawater pump can be copper tubing or flexible hose. A
flexiblesection of hose is used forthe actual connection
to the seawater pump to allow vibrational motion of the
generator set during operation. The hose should have
aninsidediameterof3/4in.(19mm).Copperlineshould
be supported within 4 in. (102 mm) of its connection to
the flexible section.
NOTE
A 5/8 in. (16 mm) waterline hose can be substituted for
the recommended 3/4 in. waterline hose.
Piping should be kept straight and as short as possible.
See Figure 6-14 for the seawater connection to the
seawater pump inlet. The seawater outlet is combined
with engine exhaust gases. (On sound shieldedunits, a
small section of molded hose is required for the
seawater inlet connection.)

Closed/Heat Exchanger
A closed, heat exchanger cooling system, the best
alternative for most applications especially if craft is to
be operated in salt waters or waters with high silt
content, is provided as part of the generator set.
Service accessibility must be provided for the heat
exchanger pressure cap. See Figure 6-15.
