ABSTRACT:
A water jet propulsion system for use with boats having an impeller duct which discharges a stream of liquid through a nozzle to propel the vessel in a forward direction. A reversal plate is provided which occludes the rearward jet opening and causes the stream to exit through a pair of reverse movement ports, one disposed on each side of the nozzle to direct the water jet from the impeller duct forwardly and preferably also slanted downwardly when the boat is to be reversed.
