Abstract
A jet propelled watercraft having a reverse thrust mechanism including a reverse thrust bucket. The hull is provided with a portion that underlies the discharge nozzle of the jet propulsion unit and which provides a continuous surface for the hull when the reverse thrust bucket is in the forward drive mode. However, when the reverse thrust bucket is moved to the reverse thrust position, a closure panel opens to provide an opening through which water may be discharged during reverse thrust operation.
Claims13
A watercraft having a hull and a jet propulsion unit supported by said hull for propelling said watercraft, said jet propulsion unit having a discharge nozzle, a reverse thrust bucket supported for movement relative to said discharge nozzle between a forward drive position and a reverse drive position wherein the water from the discharge nozzle is diverted in a forward direction so as to provide a reverse driving thrust, said hull having a portion underlying said discharge nozzle, and a movable closure plate carried directly by said underlying portion and moveable between a closed position to provide an extension of the hull that extends under said discharge nozzle and an open position to provide an opening through which the water diverted by said reverse thrust bucket may pass when operating in the reverse thrust mode.
