ABSTRACT:
An integrated nozzle is designed to deflect the jet from a waterjet pump in a watercraft before it leaves the nozzle for watercraft steering. The nozzle may be so configured to be steerable in both the horizontal and vertical planes. The integrated nozzle and steering mechanism with thrust reversal mechanism attached thereto allows a full thrust capability without appreciable friction losses inherent in conventional waterjet steering buckets.
