BOAT THRUSTER

An improved boat thruster including a diverter valve having an inlet connected to a water pump and a pair of outlets extending to either side of the boat. Each outlet includes a primary nozzle and a deflector movable to a first position wherein it allows water flow from the primary nozzle to be discharged to one side to thus thrust the boat to the opposite side. Each deflector is also movable to second and third positions for directing the primary nozzle water flow to respective secondary nozzles for discharging the water either forwardly or rearwardly to thus thrust the boat in the opposite direction. The secondary nozzles each have an exit area smaller than that of the primary nozzle.
