325 Conquest
This vessel is equipped with three bilge pumps and a
shower sump with pump and float switch (see Figure
3.1.1). The aft bilge pump and the high water bilge
pump are rated at 2,000 GPH (7571 LPH) and the
forward bilge pump at 1,100 GPH (4164 LPH). Each
pump is activated by a float switch when the water
in the bilge reaches a predetermined level.
A switch on the helm switch panel labeled
FWD
BILGE
controls pump operation. The switches
should remain in the AUTO position while in use or
operated manually by depressing the switch to the
ON
position.
The bilge pumps and the shower sump discharge
water overboard by way of thru-hull fittings. The aft
pump and emergency high-water bilge pump can be

accessed through the mechanical access hatch in the
cockpit deck (see Figure 3.1.2). The forward pump
and shower sump can be accessed by lifting the hatch
on the bottom cabin step and removing the trash can
revealing and removing the cover. Access the shower
sump pump by removing screws holding top on unit.
Bilge Pump Maintenance
Frequently inspect the area under all 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 and repeat 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 (see Figure 3.2.1). If
water does not come out of discharge hose:
1. Remove motor module to see if
the impeller rotates with the power on.
2. Remove any debris that may have
accumulated in the nozzle section or
strainer base.
3. Check hose and connection on hull side
for debris and proper connections.
