12459617 · 2025-11-04 · ·

A mixed flow water jet pump used for propulsion in boats and other water borne craft. The jet pump may be a fixed assembly or alternatively in part comprise an intake section and flexible intake section extension allowing a trimming function and where the primary input drive shaft does not pass through the intake section of the jet pump. The jet pump drive may comprise a dual or single input drive shaft system where the dual input drive train allows for much greater power delivery to the pump while maintaining reliability. The jet pump may have a sterndrive or outboard configuration using internal combustion engines or electric motors as the primary driving means.
