The outer peripheral surface of the rubber sleeve is bonded to a fiberglass ring which is bonded to an elongated annular rubber member which is in sliding contact with the inner peripheral surface of a teflon ring which in turn is bonded to the inner peripheral surface of a fiberglass sleeve. The latter sleeve in turn is bonded to the inner periphery of the upper end of a housing that is attached to the hull of a vessel. The lower portion of the rudder shaft has secured to it an annular rubber bearing that is in frictional sliding contact with a teflon ring that is secured to the inner peripheral surface of the lower end of the housing.
