Abstract

A jet powered watercraft of motorcycle-like configuration. Longitudinally aligned front and rear skis are located in spaced relation below a hull and operate to hydrodynamically lift the watercraft to a cruise position by relative water flow upon the undersides of the skis. The rear ski and a jet pump are secured as an integral unit to an engine. The rear ski includes an opening through which water passes to the jet pump, and further includes channels on either side of the opening to collect and carry away entrained air. The engine is located in the hull and is cooled by water supplied by the jet pump which it drives. The front ski is rotatable for steering and is resiliently extensible for stability in turning. The center of buoyancy of the watercraft is above its center of gravity so that the craft is self-righting. The exhaust and cooling systems are arranged to eliminate flooding despite location of portions of the engine below water when the craft is at rest. The jet pump discharge nozzle is completely out of the water in the cruise position of the craft for maximum thrust.
