Protect your valuable investment and give yourself priceless peace of mind with Megaware KeelGuard. Ultra tough, KeelGuard is designed to protect your boat's keel from excess wear and abrasion that comes from contact with sand, rocks, or concrete ramps. This easy-to-install, 5" wide, protective strip is made of a polymer composite and uses an extremely strong 3M pressure-sensitive adhesive. Once applied to your boat's keel, you can forget about it. Angled grooves in the KeelGuard produce hydrodynamic channels, creating air pockets and providing a slicker surface. Lifetime "no hassles" warranty.
