A bushing assembly is receiveable in the cavity of the housing structure. The bushing assembly includes a spindle having an inner surface defining a passageway for receiving the propeller shaft therethrough and an outer surface having a plurality of circumferentially spaced fin pairs extending therealong. Each fin pair includes a first fin extending from the outer surface of the spindle and a second fin extending from the outer surface of the spindle at a predetermined angle to the first fin.
