ECTION
If the liquid level in the bilge is higher than
normal and the bilge pump empties the bilge
when you use the ON switch, either the breaker
for the automatic bilge pump circuit has blown
or the float switch is not operating properly.
Have it checked immediately. If the ON switch
does not operate the pump, DO NOT use the
boat until the problem is corrected.
The emergency high water bilge pump and float
switch are wired to the high water bilge alarm.
Should the pump be activated by water in the sump,
the alarm will sound. If alarm sounds, immediate
attention to the engine room is required.
The bilge pump automatic circuit is protected by a
breaker on the main DC breaker panel located in
the engine compartment (See Fig. 6.7.1 & 6.11.2).
The bilge pump manual circuit is protected by a
breaker in the aft EIM box located in the engine
compartment.

AINTENANCE
Frequently inspect the area under the float switches
to ensure they are free from debris and gummy bilge
oil. To clean, soak in heavy duty bilge cleaner for 10
minutes, agitating several times. Check for
unrestricted operation of the float. Repeat the
cleaning procedure if necessary.
Inspect the bilge pump intakes and keep them
free of dirt or material which may impede the
flow of water through the pump. To clean the
pump strainer, depress the lock tabs on both sides
of the pump and lift the pump motor.

To prevent buildup of gasoline fumes to the
explosive level in the engine compartment, the
bilge blowers must be run for at least four (4)
minutes before starting the engine and kept
running at all times when the engine is running to
insure that there will be adequate ventilation when
you are moving slowly.
The bilge blower is protected by a breaker in the aft
EIM box located in the engine compartment (See
Fig. 6.7.1 & 6.11.2).
