ABSTRACT:
A reverse thrust bucket assembly for a water jet propulsion unit wherein the reverse thrust bucket and the discharge nozzle are configured to provide a good seal in the reverse thrust position of the reverse thrust bucket while, at the same time, permitting the reverse thrust bucket flow directing surface to have an uninterrupted curved area without an offset sealing flange that could offer flow resistance when being shifted between its positions. In addition, the steering nozzle and discharge end of the jet propulsion unit are configured so as to preclude any leakage in this area.
