PROPELLER ASSEMBLY WITH NOISE REDUCING HUB ARRANGEMENT A propeller assembly (10) is provided for mounting on a rotatable propeller shaft (12) having a terminal end (14). The propeller assembly (10) includes a housing structure (22) extending along a longitudinal axis (43) and having first (42) and second (40) ends. The housing structure (22) includes an inner surface 10 (36) defining a cavity (37) and an opening (37a) in the second end (40) in communication with the cavity (37). A bushing assembly (60) has first (73) and second (75) ends and includes an outer surface (74) engageable with the inner surface (36) of the housing structure (22). An adaptor (90) has first (87) and second (89) sides and is adapted for receipt on the propeller shaft (12). The 15 adaptor (90) has an enlarged portion (96) having a diameter greater than a diameter of the opening in the second end (40) of the housing structure (22). A nut (16) is receivable on the terminal end (14) of the propeller shaft (12). The nut (16) is threadable on the propeller shaft (12) to a tightened configuration wherein the nut (16) engages the adaptor (90) and maintains the propeller assembly (10) on 20 the propeller shaft (12). The nut (16), in the tightened configuration, the first side (87) of the adaptor (90) engages the second end (75) of the bushing assembly (60) and the enlarged portion (96) of the adaptor (90) is spaced from the second end (40) of the housing structure (22).
