McGard: Outboard Motor Locks

McGard outboard motor locks are designed to lock the outboard onto the transom of the boat. Simply replace one of the mounting nuts with a McGard locking nut. McGard outboard motor locks are identical in quality and construction to our stern drive locks. A free-spinning collar turns if attacked by gripping tools, protecting you against costly outboard motor theft and the resulting inconvenience. OUTBOARD MOTORTHREADMercury/Mariner 40 HP and larger (2 stroke) Mercury 25 HP and larger (4 stroke) Suzuki 150 - 300 HP1/2-20Yamaha 40 HP and larger (2 stroke) Yamaha 30 HP and larger (4 stroke) Honda 40 HP and larger Suzuki 25 - 140 HP (2005 and newer)M12 x 1.25Johnson/Evinrude 40 HP and larger (2 stroke)1/2-13
