  3. Position the Guard: Slide the skeg protector firmly onto the skeg until it is fully seated.
  4. Align and Secure Hardware: Align the mounting holes on the protector with the threaded holes. Insert the included self-locking bolts.
  5. Tighten Bolts: Using the provided hex wrenches, tighten the bolts evenly until the skeg protector is held firmly in place. Do not overtighten.

Troubleshooting & FAQ

How do I know if this skeg guard will fit my specific Mercury engine?
This skeg guard fits a wide range of Mercury/Mariner 75-300 HP outboards (1996-Present). To ensure a perfect match, please consult the "Compatible Engine Models" table on this page. Crucially, you must have at least 2-3 inches of your original skeg remaining for proper installation.
