Abstract
A propeller assembly includes an interchangeable drive sleeve, an inner hub, a biasing member forcing the drive sleeve into contact with the inner hub, and a propeller including an outer hub in which the drive sleeve and inner hub are inserted. In an exemplary embodiment, the drive sleeve includes a plurality of teeth that engage a plurality of teeth on the inner hub. The spring is configured to permit the drive sleeve to move axially away from the inner hub upon the occurrence of a sufficient torque and allow the drive sleeve to rotate relative to the inner hub. A bore extends through drive sleeve, and a plurality of grooves are in an inner diameter surface of the drive sleeve bore. These grooves are configured to mate with splines on a propeller shaft. The inner hub includes a plurality of keys and the outer hub includes a plurality of complimentary keyways to limit relative movement between the inner hub drive flange and the outer hub.
