Systems

Bilge Pumps

The additional weight of water in the boat can adversely affect handling characteristics creating an unsafe

condition. In addition the sloshing water may be corrosive to the boat’s systems.

Since water is heavy (over 8 pounds per gallon) it must not be allowed to accumulate within the vessel.

It is highly recommended there be at least one hand operated pump on the vessel in the

event of a bilge pump failure.

General Maintenance

On a regular basis you should:

1. Inspect the bilge pump intake and keep it free of dirt or material which may impede the flow of water through the

pump.

– To remove the pump strainer, depress the lock tabs on both sides of the pump and lift the pump motor.

2. Check the bilge pump float switch by moving it manually.

– The float switch should move freely without sticking or binding. If it doesn’t, service or replace the switch

before using the boat.

3. The bilge pump should start when the float switch is raised and should stop when lowered.

– If the pump does not start, reset the circuit breaker(s). If the pump still fails to start, replace the float switch

before using the boat.

– If you have to remove the float switch, verify proper operation of the new switch.

4. After inspection reinstall the unit.

Electric Bilge Pumps

It is illegal to discharge oily bilge water into the waters of the United

States. Bilge oil spills must be mopped up and the oil and rags prop-

erly disposed of.

There is one bilge pump in each boat, located on the centerline in the engine compartment. All models

except the Lancer 20 use the Rule 1000 GPH model. The Lancer 20 uses the 800 GPH model.

The pump may be operated in the “manual” mode by placing the bilge pump switch, located on the helm

control panel, to the ON position. The indicator light on the switch illuminates indicating the pump is ener-

gized.

Do not run a bilge pump for more than a few seconds in a dry environment. Damage to

the pump may result.

The bilge pump is normally wired directly to the HOUSE battery for operation in the automatic mode. In

automatic mode, the bilge pump starts pumping as the water level reaches the bilge pump float switch. The

HOUSE battery switch must be in the ON position for the system to work.
