Installation Notes
- Clean the skeg thoroughly, removing any marine growth, dirt, or loose paint.
- Slide the skeg guard over the existing skeg to confirm a snug and proper fit. Ensure it sits flush against the gearcase.
- With the guard in place, use the pre-drilled holes in the guard as a template to mark drilling locations on your skeg.
- Remove the guard and carefully drill the marked holes using a bit appropriately sized for the included 1/4" hardware.
- Apply a marine-grade sealant (like 3M 5200) to the inside of the guard and around the drilled holes to prevent water intrusion.
- Position the guard back onto the skeg, align the holes, and install the mounting bolts. Tighten them evenly until secure, but do not overtighten.
- Wipe away any excess sealant and allow it to cure as per the manufacturer's instructions before use.
Troubleshooting & FAQ
Will this fit my specific engine model if it's not listed?
To ensure compatibility, your engine's model, horsepower, and year must match the ranges provided in the "Engine & Model Compatibility" table. Do not purchase if your model is not explicitly listed, as skeg shapes can vary significantly.
Is drilling required to install this skeg guard?
Yes, this is a bolt-on guard that requires drilling two holes into your existing skeg. The included hardware is specifically designed for this purpose. The process is straightforward for those comfortable with basic mechanical tasks.
Can this be installed on a skeg that is already broken or partially missing?
This guard is designed to fit over an existing, intact skeg. It can cover and protect a skeg with minor damage (e.g., chips, scrapes), but it requires at least 2-3 inches of the original skeg remaining to properly mount and secure.
What is the difference between this 316 stainless steel guard and an OEM part?
This aftermarket guard is made from high-quality 316 stainless steel, known for its superior corrosion resistance compared to other steel grades. While OEM parts guarantee a perfect fit, our guard is built to meet or exceed original specifications for durability and protection, often at a better value.
How can I tell if my existing skeg is damaged and needs a guard?
Inspect your skeg for visible signs of damage like deep scratches, gouges, cracks, or a bent profile. Any significant impact from rocks, sand, or debris can compromise its integrity and affect steering. A guard can prevent further damage or cover existing cosmetic flaws.
