CA 1266588

Abstract of the Disclosure An anti-theft device for a marine propeller has a spinner placed over the propeller nut which secures the propeller to the propeller shaft, and the spinner is held in place against unauthorized removal by a lock pin projecting from the propeller nut into an annular recess in the spinner, enabling the spinner to spin freely relative to the propeller nut while capturing the spinner against axial movement which would expose the propeller nut for unauthorized wrenching, the spinner including a radially extending access passage for gaining access to the lock pin with an authorized drive member to move the lock pin out of the annular recess for selective release of the spinner from the propeller nut and authorized access to the propeller nut for wrenching.
