ABSTRACT:
A number of embodiments of steering nozzle and reverse thrust bucket arrangements for jet propelled watercraft. The steering nozzle, in addition to being mounted for steering movement about a vertically extending steering axis is also mounted for trim adjustment about a horizontally extending axis. A cooperating reverse thrust bucket provides reverse thrust operation. The reverse thrust bucket is either mounted on the hull of the watercraft independently of the jet propulsion unit, on the outer housing of the jet propulsion unit independently of the steering nozzle or on the steering nozzle.
