ABSTRACT:
A system for employing the propulsion system of a boat for bilge pumping. A tube surrounds the submerged propeller of the boat and extends forwardly to an inlet beneath the boat. An opening through the hull of the boat is provided in communication with the tube. A door controls communication between the hull and tube and alternatively between the inlet and the tube. A float within the hull controls the door depending on the level of water within the hull. A flow sensor locks the door in the closed position when flow is not experienced through the tube to the propeller.
