McGard Outboard Motor Stern Drive and Propeller Theft Protection

Extremely resistant, safe and easy-to-use anti-theft system designed for outboard motors, stern drives or propellers. Simply replace one of the mounting bolts with the McGard locking nut/collar. The free-spinning collar rotates freely and prevents removal. Only the McGard key included in the package can be used to unscrew the device.
