Sea Water Washdown Pump
Your boat might be equipped with a 12 VDC sea water
washdown system. The sea water pump and sea
strainer are located in the aft bilge area. The pump
and sea strainer can be inspected and serviced
through the deck hatch just forward of the splashwell
bulkhead. The washdown system includes a seacock
that can be closed if you service the system while the
boat is in the water.
The washdown pump output can be accessed through
the hose fitting located on the interior transom bulk-
head.
The pump is controlled by an OFF-ON rocker switch
located on the helm station switch panel. The pump
power circuit is protected by a 10-amp push button
breaker located above the rocker switch.
The pump is equipped with a pressure switch that acti-
vates the pump on demand when the rocker switch is
in the ON position.
Turn off the sea water washdown pump when it is not
required to avoid discharging the house battery.
Turning the house battery OFF-ON switch to the OFF
position at the end of your mission will cut power to the
sea water washdown pump.
