3.2.4 Water Lines
Water lines from the seacock to the engine-driven
seawater pump are usually constructed of flexible hose.
Connect a flexible section of hose to the seawater pump
to allow the generator set to vibrate during operation.
Support a nonflexible water line within 102 mm (4 in.) of
its connection to the flexible section.
Keep the seawater hose as straight and short as
possible. If the hose is too long, usually over 4.6 m
(15 ft.), water suction problems may occur. See
Section 7 for the inlet water line hose size and the
seawater connection to the seawater pump inlet. Avoid
running the inlet pipe above the generator. See
Figure 3-5 for the seawater hose connection to the
seawater pump inlet.
