Before starting the engine, press the bilge pump
switch so that the switch light comes ON. Make sure
the pump is working by opening the engine
compartment, listening to hear the pump running
and check to see that liquid is being pumped out
from the hull discharge (See Fig. 2.8.1). If the bilge
has more liquid than normal, see Maintenance
Section for locating and correcting the problem.
Except for checking the operation of the bilge pump
using the ON position, leave the switch in the OFF
(AUTO) position. In the OFF (AUTO) position, when
the bilge liquid is deep enough to activate the float
switch, the bilge pump turns on and pumps out the
bilge liquid until the float switch drops and shuts off
the pump.
If the liquid level in the bilge is higher than
normal and the bilge pump empties the bilge
when you use the ON switch, 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 is protected by a fuse in the
electronic interface module located in the engine
compartment (See Fig. 6.9.2).

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.

ILGE LOWERS
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 fuse in the
electronic interface module located below the
control station in the sleeping berth (See Fig. 6.9.2).
