McGard 74056 Propeller Lock

Protect yourself against expensive propeller theft with our newly designed lock. Featuring the same patented design as the stern drive and outboard motor locks. A free-spinning collar will turn if attacked by gripping tools without loosening the lock. It is constructed of naval brass and hardened stainless steel for maximum security. Once installed the propeller lock offers 24 hour a day protection.
