ABSTRACT:
A shell made up of opposed halves is fitted over the propeller screw of the motor on the boat. This shell then becomes an enclosure with inlet and outlet openings at the ends. This shell with the propeller screw forms a pump with the propeller screw pumping water through the shell and through an outlet hose which is extended to the shore. One form has the inlet and outlet openings on the axis of the propeller screw and other forms include the outlet arranged tangentially or angularly. A hose can be connected to the inlet opening for bailing a boat.
