Bilge Pump Testing
Bilge pumps must be tested often to verify they are working properly. To test a
bilge pump, activate the dash-mounted switch and verify that the bilge water is
being 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 as follows:
Checking for clogging debris:
1. Remove the power cartridge:
a. Lift the tab while rotating the fins
counterclockwise.
2. Lift out the power cartridge.
3. Clear debris from the outer housing.
4. Re-install 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 cams on either side of the car-
tridge with the slots on the outer hous-
ing and press the power cartridge into
the housing while twisting clockwise.
5. Check reinstallation by trying to twist the
fins counterclockwise without lifting the
tab. The cartridge should stay in place.
Autofloat Switches
Automatic bilge pumps use electromagnetic float (autofloat) switches to automati-
cally activate the pump whenever bilge water rises above a preset level. An
autofloat switch is mounted next to the bilge pump, and is wired directly to the
battery so it will normally function even when the boat is completely shut down
and left unattended.
Your Autofloat switch must be tested often for proper operation as follows:
Float Switch Test:
1. Push the float switch test
button up to activate the
bilge pump.
2. If the pump does not turn on,
check the inline fuse. If the
fuse is good but the switch
doesn’t work, it may indicate
a bad switch or possibly a
low battery.
3. Push the test button all the way
down to return the float switch
back into the auto mode.
