Bilge Pump Testing
TAB
• The bilge pumps are critical to the safety of your boat.
• Check the bilge pumps often to make sure they are working.
Test each pump often as follows:
1. Turn on the bilge pump switch at the helm.
2. Any water in the bilge should pump overboard.
• If the pump motor is running but not pumping inspect the discharge hose for a kink or collapsed area.
• If no problems are found, check the bilge pump housing for clogging debris as follows:
1. Remove the power cartridge:
a. Lift the tab while rotating the fins counter-clockwise.
b. Lift out the power cartridge.
c. Clear the outer housing of debris.
2. Reinstall the power cartridge:
a. Make sure the "O" ring is properly seated.
b. Coat the "O" ring with a light film of vegetable or mineral oil.
c. Align the cams on either side of the power cartridge with the two slots on the outer housing
d. Press the power cartridge into the housing while twisting clockwise.
3. Check the reinstallation by trying to twist the fins counter-clockwise without lifting the tab; the cartridge should
stay in place.
