E PUMP DISCHARGE
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. 2.6.1). 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 bilge pump is protected by a fuse in the
electronic interface module located behind the
control station (See Fig. 6.6.3).

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.
