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.
