Marine spare part and equipment for McGard Outboard Stern Drive and Propeller Theft Protection.
Extremely durable, 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. The McGard key included in the package is required to remove the anti-theft device.
