A marine propulsion system for shallow waters, swamps, savannahs and the like includes a rotating propeller shaft supporting a propeller. An anti-cavitation body defines a partial cylinder having a longitudinal axis adjacent to the propeller. The propeller generates a vacuum between the anti-cavitation body and a surface of a water body. First and second wings adjacent to edges of the anti-cavitation body are generally planar and operatively angled towards the bottom of a water body. The first and second wings are adjusted to run below the water body surface and seal the anti-cavitation body to maintain generated vacuum. A first thread is cut in a first helical direction at an end of the rotating propeller shaft adjacent the propeller, and slightly more distal therefrom a second thread is cut in a second helical direction opposed to the first thread helical direction. The second thread drives matter away from the bearing.

The present disclosure relates to a vessel propelling mechanism. In one aspect, a vessel propelling system includes a motor and a waterjet system. The waterjet system is coupled to the motor and includes a stator with a plurality of blades. A first blade of the plurality of blades has a shape that is different than remaining blades of the plurality of blades, the shape of the first blade allowing a driving mechanism of the motor to be coupled to a shaft within the waterjet system.
