Bilge Pump Testing
Bilge pumps must 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 from 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 car-
tridge with the two slots on the outer housing and
press the power cartridge into the housing while
twisting clockwise. To ensure proper reinstallation,
attempt 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 automatically activate the pump whenever
water accumulates above a preset level in the bilge. An autofloat switch is mounted next to the bilge pump it acti-
vates, and is wired directly to the battery so it will normally function even when the boat is completely shut down and
left unattended. Autofloat switches must be tested often for proper operation as follows:
Float Switch Testing
1.
Push the float switch test button up to
activate the bilge pump.
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.
2. Push the test button all the way down to
return the float switch back to auto mode.
