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 forward emergency high water pump and float
switch, located under the cabin entry steps, are
wired to the high water alarm. Should the pump be
activated by water in the forward bilge, the alarm
will sound. If the alarm sounds, immediate attention
to the forward bilge area is required.
The bilge pump automatic circuit is protected by a
breaker on the main DC breaker panel located on
the cockpit floor storage aft bulkhead (See Fig.
6.6.1). The bilge pump manual circuit is protected
by a fuse in the accessory fuse block located
behind the access panel above the MDP in the
STBD storage area.

AINTENANCE
Frequently inspect the area under the float switch
to ensure it is 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 intake and keep it 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.

ROUBLESHOOTING
:
If water does not come out of discharge hose:
1. Check the “BILGE PUMP” and “FWD SUMP”
fuses on the bilge component board (see Fig.
6.4.1) to ensure they have not blown.
2. Remove the motor module to see if the impeller
rotates with the power on.
SINKING HAZARD – Ensure the bilge pumps are
operating properly.
! WARNING
Run bilge pumps in the manual position only as
long as necessary to remove water. Running bilge
pumps dry can damage the pump motor.

A bilge pump and float switch are located in the
bottom of the bilge (Fig. 4.2.1). The bilge pump can
be manually activated from the switch located on
the Starboard Switch Panel at the helm.
Before starting the engine, push up on 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 checking to see that liquid is being
pumped out from the hull discharge (See Fig. 2.9.1).
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
by 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.
