ABSTRACT:
A waterjet propulsion system for a vessel permits stationary mounting of the pump within the vessel hull, and further allows minimizing the size and weight of the pump casing, by providing a pivotably moveable, hull mounted and supported, steering and reversing sleeve mechanism positioned to receive the waterjet flow from a waterjet nozzle and to redirect at least a portion of that flow for steering and production of reverse thrust. The sleeve structure also permits all machinery for achieving control of steering and reverse thrust to be placed in protected locations such as being faired into the sleeve or within the vessel hull. Protection of linkages and reduction of the weight thereof is also provided.
