Protect yourself against expensive propeller theft with a McGard propeller lock, featuring the same patented design as our stern drive and outboard motor locks. A free-spinning collar will turn if attacked by gripping tools without loosening the lock. Constructed of naval brass and hardened stainless steel, once installed our propeller lock offers maximum security for 24 hour protection.
