Abstract
A waterjet propulsion pump (,) is mounted in an opening in a fully submerged intermediate transom (,) located forward of the stern transom (,) and at the aft end of a dependent structural pod (,) on the hull bottom with the pump discharge nozzle (,) lying aft of the intermediate transom. A steering nozzle (,) is mounted on the discharge nozzle (,) for pivotal movement about an axis that lies in a vertical plane. At least one reversing deflector (,or,and,) is mounted for pivotal movement about an axis that is perpendicular to the vertical plane. A rotatable steering shaft (,) operated by a steering actuator located with the hull (,or,) is coupled to the steering nozzle (,or,). A hollow reversing shaft (,) is received telescopically over a portion of the steering shaft and is translatable axially relative to the steering shaft by a reversing actuator (,) located within the vessel hull. A mechanical linkage (,and,) coupled between the reversing shaft and the reversing deflector pivots the reversing deflector between an inactive position and an operative position. Fairings (,) fair to the lines of the pod and to each other cover the sides and bottoms of discharge nozzle, steering nozzle and reversing deflector, and the steering and reversing shafts.
