A water jet apparatus having a mechanism for providing additional lateral thrust when a boat is moving in reverse. A steering nozzle is pivotably mounted at and in flow communication with the outlet of a flow-through housing, and has a pair of opposing side thrust nozzles. The water flow exiting the steering nozzle is reversed by a reverse gate which covers the main outlet of the steering nozzle and by a reverse nozzle incorporated as part of the steering nozzle. The reversed flow exits the steering nozzle via the reverse nozzle, which directs the reversed flow forward and downward. When the steering nozzle is turned a predetermined angle to one side in reverse, the side thrust nozzle on the opposing side is swung into the path of water flow exiting the housing outlet. In this position, the side thrust nozzle directs a portion of the flow exiting the housing outlet in a direction approximately at a right angle relative to the centerline of the turned steering nozzle to provide additional lateral thrust directed toward the one side.

[ I claim:] [1.]1. A water jet apparatus comprising:a flow-through housing;a steering nozzle pivotably mounted to and in flow communication with said housing, said steering nozzle being pivotable between first and second steering positions and comprising an outlet, a reverse port upstream of said outlet, and first and second side ports upstream of said reverse port on opposing sides of said steering nozzle; anda reverse gate pivotable between first and second shift positions, said reverse gate in said first shift position being removed from the path of water flowing toward said steering nozzle outlet and in said second shift position being in the path of water flowing toward said steering nozzle outlet.
