  • Patent number: 4223630
    Abstract: The invention pertains to reversing apparatus for hydraulic jet marine drives utilizing a pivoted steering nozzle and a reversing gate adapted to divert a jet of water into a reversing nozzle. The reversing nozzle is rotatably mounted upon the steering nozzle and utilizes orientation apparatus fixed with respect to the axis of the steering nozzle such that rotation of the steering nozzle in one direction produces rotation of the reversing nozzle about its axis in the opposite direction. The relative movements of the steering and reversing nozzles produces force vectors in the nozzles in a common lateral direction with respect to boat movement wherein a high degree of boat control while being reversed is achieved at low pumping capacity.
