Severe keel damage is a common boating nightmare. Rocks, ramps, sand, coral and debris in the water can all take a toll on your boat or personal watercraft. The KeelGuard is an easy-to-install keel protector that is tough enough to take the abuse so your boat won't have to. Developed by a boat designer who spent years investigating the best protective materials, this unique guard adheres along the keel using extremely strong 3M pressure sensitive acrylic adhesive - the same adhesive used by NASA on the space shuttle. Independent radar speed tests have demonstrated smaller boats and personal watercraft protected with KeelGuard consistently achieves higher top-end speed. The patent hydrodynamic channel ribbing enhances handling an improves tracking. The 8-ft. KeelGuard fits boat lengths of 21'-22' and PWC's. Scotch-Brite pad, primer and burnishing tool included.
