Marine spare part and equipment for McGard Outboard Stern Drive and Propeller Theft Protection.
Extremely resistant, easy to use, and secure anti-theft protection system for outboard units, stern drives, or propellers. Simply replace one of the mounting nuts with a McGard locking nut/collar. The free-spinning collar rotates independently, making disassembly impossible. Only with the included McGard key can the anti-theft device be unscrewed.
