Propeller lock
Antitheft protection when in use, in storage, and during transport. Protect your customers with McGard antitheft propeller locks with the same patented design as our stern drive and outboard motor locks. An attempt to force open this lock causes a loose sleeve to rotate, but the lock remains fixed and your propeller is protected against theft. Our propeller locks are made from special corrosion resistant brass with specific alloy fractions and hardened stainless steel for an assured maximum level of security.
Once fitted, our propeller lock provides permanent protection.
