Abstract
A shock absorbing drive sleeve (402, FIGS. 28+) mounts a marine drive propeller (12) to a propeller shaft (22) and has an asymmetric spring rate such that the sleeve has a higher spring rate and greater torque bearing capability for the forward boat direction, and a softer spring rate and greater shock absorption for the reverse boat direction, to protect the weaker reverse drive components of the gear train.
