Product Description:
Protect your boat’s propeller from theft with the McGard Boat Propeller Lock, a trusted security solution engineered with the same patented design used in McGard’s stern drive and outboard motor locks. This robust lock replaces your prop nut with a precision-crafted unit made from corrosion-resistant naval brass and hardened stainless steel, ensuring durability and long-lasting marine protection.
The patented free-spinning collar actively thwarts gripping tools and tampering attempts, making unauthorized removal virtually impossible without the unique key. Designed for ease of use, simply install once and leave the lock on—no need to remove it before every boat outing, allowing hassle-free operation without compromising security.
Compatible with a wide range of stern drives and outboard motors from leading manufacturers including Yamaha, Honda, Suzuki, and Johnson/Evinrude, this lock fits thread size M18x1.5, making it ideal for many popular marine engines.
Crafted in the USA to meet or exceed OEM standards, the McGard Boat Propeller Lock offers boat owners peace of mind by securing a vital component of their vessel against theft, corrosion, and wear.
