ABSTRACT:
A marine propulsion system comprised of a housing unit having forward and rearward openings, a rotational unit, having forward and rearward openings and having an inner and outer periphery, rotatably secured in the housing unit such that the forward and rearward openings are aligned with the forwards and rearward openings of the housing unit, a plurality of blades rigidly secured to the inner periphery of the rotational unit, and drive means which rotate the rotational unit within the housing unit. Operation of the drive means causes the rotation of the rotational unit and the blades direct water into the forward openings of the housing unit and the rotational unit and out the rearward openings of the housing unit and rotational unit, thereby creating thrust.
