Abstract

A water jet apparatus having a single drive shaft rotatably supported by a pair of bearings installed in an inlet housing. The impeller is securely mounted on a splined end of the drive shaft which extends out of the inlet housing in the aft direction. The drive shaft is not supported by the stator housing, thereby eliminating the need to install bearing inside the stator housing during assembly. Oil seals are arranged between the drive shaft and an inlet housing projection which extends into a cavity formed in the front end of the impeller.
