Bilge Pump Testing
•
The bilge pumps are vital to the safety of your yacht.
•
Test the bilge pumps often to make sure they are working properly.
1. One at a time, turn On the bilge pump switches at the helm.
2. Make sure that water in the bilge is pumped overboard.
If there is water in the bilge and a pump motor is running, but not pumping, inspect the discharge hose for a kink or
collapsed area.
If the discharge hose looks okay, check the bilge pump and strainer for clogging debris.
Checking the bilge
pump and strainer for
clogging debris:
1. With your thumb and
forefinger, squeeze the
holding tabs on each
side of the strainer.
2. Lift out the bilge pump.
3. Check the pump and
strainer and clear any
debris.
Reinstalling the bilge
pump:
1. Align the tabs on the
strainer with the slots on
the pump.
2. Press down firmly until
the tabs click into place.
3. Make sure the bilge
pump is locked into
place.
Autofloat Switches
•
Each automatic bilge pump features an autofloat
switch.
•
The autofloat switch turns the pump On when water
rises above a preset level.
•
Each autofloat switch is normally located next to the
bilge pump it controls.
•
The autofloat switches should be tested often.
Autofloat switch testing:
1. Twist either of the white plastic knobs one quarter
turn to lift the float and turn On the bilge pump.
•
If the pump does not turn On, check the push-to-
reset circuit breaker.
•
If the circuit breaker is good, but the switch still
does not work, it may mean the switch is bad, or the
battery is dead.
