ABSTRACT:
A thin wall sleeve is provided including an inside diameter greater than the outside diameter of the rear terminal end of a marine outdrive lower unit propeller drive housing portion and the adjacent front terminal end of an associated marine propeller hub. The sleeve is mounted in position with its opposite ends telescoped over the housing portion and hub terminal ends and the longitudinal mid-portion of the sleeve bridging the axial spacing therebetween. The sleeve is mounted from the housing portion terminal end, for example, by an adhesive band layer, maintaining the inside diameter surfaces of the sleeve radially spaced outward of the outer surfaces of the housing portion rear terminal end and the hub front terminal end loosely rotatably received within the sleeve.
