ABSTRACT:
A propulsion system for a watercraft includes an upwardly inclined drive shaft to improve acceleration. The upwardly inclined orientation of the impeller shaft, and thus a similar orientation of the discharge stream exiting the jet propulsion system, causes the bow of the watercraft to ride out of the water when the watercraft is planing. The watercraft thus has less surface contact with the water, and travels faster.
