A propeller assembly is provided for mounting on a rotatable propeller shaft of a watercraft. The propeller assembly includes a hub structure extending along a longitudinal axis. The hub structure includes an outer surface having a plurality of circumferentially spaced propeller blades projecting therefrom and an inner surface having a longitudinally extending keys projecting therealong. An adaptor has an inner surface defining a passageway for receiving the propeller shaft therethrough and an outer surface having longitudinally extending keys extending therealong. A tubular bushing interconnects the adaptor to the hub structure. The tubular bushing has a first set of keyways for receiving corresponding keys of the adaptor in a mating relationship and a second set of keyways for receiving the keys of the hub structure in a mating relationship.
