    摘要: A marine propulsion mechanism submersible in water for driving a water craft is disclosed. The propulsion mechanism includes a streamlined housing having a fluid inlet opening positioned between the forward and rearward ends of the housing in addition to a fluid discharge opening at the rearward end. A tubular support is joined to the housing for mounting such upon a water craft. An inlet scoop extends outwardly from the housing and directs water to the fluid inlet opening. The scoop is provided with a rigid tube having a first end secured about the fluid inlet opening and a second end terminating at forwardly directed duct remote from the exterior surface of the housing. The scoop further includes a screen set within the forwardly directed duct for preventing debris from entering the housing interior. An impeller is rotationally secured within the housing adjacent the fluid inlet opening. Rotation of the impeller draws water through the inlet opening and discharges it through the outlet with jet-like force. In the principal embodiment of the invention, a geared transmission is secured within the housing for transmitting the energy of an above-board electric motor to a pair of impellers. In a second embodiment of the invention, an electric motor unit is positioned within the housing for rotating a single impeller.
