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 problems are
found, check the bilge pump housing for clogging debris:
To remove the power cartridge:
1. Lift the tab while rotating the fins counterclockwise 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 cartridge with the two slots on the outer housing. Press the power
cartridge into the housing and twist clockwise. Ensure proper reinstallation by attempting to twist the fins coun-
terclockwise without lifting the tab. The cartridge should stay in place.
TAB
If applicable, the autofloat switch should also be checked often for proper operation. Lift the float by turning the plas-
tic insert where the wires enter the housing, 1/4 turn counterclockwise (Fig. 3).
As the float is lifted, the bilge pump should turn on. If lifting the float does not turn the pump on, check the inline
fuse. If the fuse is good but the switch does not work, it may indicate a bad switch or possibly a low battery.
