Bilge Pump Locations
Bilge Pump Testing
Bilge pumps should be checked often to verify that they are
working properly. To test a bilge pump’s operation, activate the
dash-mounted switch and 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 as follows:
1. Remove the power cartridge:
a. Lift the tab while rotating the fins counterclockwise.
b. Lift out the power cartridge.
c. Clear the outer housing of debris.
2. Reinstall the power cartridge:
a. Make sure the “O” ring is properly seated.
b. Coat the “O” ring with a light film of vegetable or
mineral oil.
c. Align the two cams on either side of the power
cartridge with the two slots on the outer housing
and press the power cartridge into the housing
while twisting clockwise.
d. To ensure proper reinstallation of the power cartridge, attempt to twist the fins counterclockwise without
lifting the tab: The cartridge should stay in place.
Autofloat Switches
•
Automatic bilge pumps use an electromagnetic float (autofloat)
switch to automatically activate the pump whenever water
accumulates above a preset level in the bilge.
•
Autofloat switches are mounted next to the bilge pump it
activates, and are wired directly to the battery so they will
normally function even when the yacht is completely shut
down and left unattended.
•
Autofloat switches should be tested often for proper operation
as follows.
