Outboard jet drive for watercraft

摘要

A jet propelled watercraft having an outboard motor type of jet propulsion unit. The jet propulsion unit is disposed in substantial part forwardly of the transom and beneath the undersurface of the hull for improving its pumping efficiency. The jet propulsion unit is driven by a transmission including a drive shaft having a pivotal joint. The jet propulsion unit is pivotal relative to the engine about an axis containing the axis of the universal joint so that the water inlet opening may be swung upwardly through an opening in the undersurface of the hull which is above the water level for clearing foreign objects from the jet propulsion unit water inlet opening.
