Abstract

A steering system for water craft having jet propulsion. A stator outlet (16a) discharges water into a steering nozzle (12) which is pivotably mounted on a nozzle housing (8). The internal diameters of the stator outlet and the steering nozzle form a tapered passage for efficient water flow. A seal (27) may be incorporated between the steering nozzle and the nozzle housing.
