Bilge Pump System

Your yacht is equipped with six
impeller-type bilge pumps. The
bilge pumps are controlled by auto-
matic bilge pump switches (auto-
float switches) and/or switches on
the dash panel.
The autofloat switches activate
whenever water accumulates above
a preset level in the bilge. They are
wired directly to the battery and
will normally function even when
the yacht is completely shut down
and unattended, such as when the
yacht is moored at a marina.

Bilge Pump Maintenance

Bilge pumps should be checked
often to verify that they are working
properly. To check a bilge pump's
operation, activate the dash-
mounted switch. Verify that water
in the bilge is pumped overboard. If
bilge water is present and the pump
motor is running but not pumping,
inspect the discharge hose for a
kink or collapsed area. If no prob-
lems are found, check the bilge
pump housing for clogging debris:
To remove the power cartridge:
1. Lift the tab while rotating the fins counter-clockwise and lift
out the power cartridge (Fig. 1).
2. Clear the housing of debris.
To reinstall the power cartridge:
1. Make sure the "O" ring is properly seated and coat
the "O" ring with a light film of vegetable oil or
mineral oil (Fig. 2).
2. Align the two cams on either side of the power car-
tridge with the two slots on the outer housing. Press
the power cartridge into the housing and twist clock-
wise. Ensure proper reinstallation by attempting to
twist the fins counter-clockwise without lifting the
tab. The cartridge should stay in place.
