摘要 |
Two embodiments of improved jet drive units for watercraft wherein the jet drive impeller shaft is coupled to the engine drive shaft by a slip spline connection for facilitating removal of the jet drive unit for servicing without removal of the engine. In addition, an improved connection is provided between the impeller shaft and the impeller that dispenses for the need for splines and thus permits a smaller impeller hub and a greater efficiency jet drive unit.
