Abstract: A propeller assembly is provided for mounting on a rotatable propeller shaft having a terminal end. The propeller assembly includes a housing structure extending along a longitudinal axis and having first and second ends. The housing structure includes an inner surface defining a cavity and an opening in the second end in communication with the cavity. A bushing assembly has first and second ends and includes an outer surface engageablc with the inner surface of the housing structure. An adaptor has first and second sides and is adapted for receipt on the propeller shaft. The adaptor has an enlarged portion having a diameter greater than a diameter of the opening in the second end of the housing structure. A nut is receivable on the terminal end of the propeller shaft. The nut is threadable on the propeller shaft to a tightened configuration wherein the nut engages the adaptor and maintains the propeller assembly on the propeller shaft.

Abstract: A propeller assembly is provided for mounting on a rotatable propeller shaft of a watercraft. The propeller assembly includes a hub structure having a plurality of circumferentially spaced blades projecting therefrom and an inner surface defining a passage. An adaptor is receivable in the passage of the hub structure. The adaptor a plurality of key pairs extending along the outer surface thereof the adaptor which define slots for receiving inserts therein. An inner portion of the first side of each insert forms mating relationship with first portion of the first sidewall of a first key of a corresponding key pair and an inner portion of the second side of the insert forms a mating relationship with the first portion of the second sidewall of a second key of the corresponding key pair with the insert received in the corresponding slot.
