- File any spurs or jagged edges on the damaged skeg to ensure a smooth, proper fit.
- Place the skeg guard onto the skeg. Gently tap it with a leather, rubber, or wooden mallet until it is fully seated.
- Use the pre-drilled holes in the guard as a template to drill 1/4" holes through your skeg.
- Install the stainless steel mounting bolts and nuts using the supplied hex key tool.
- Apply the included Loctite thread locker to the bolt threads before final tightening to prevent loosening from vibration.
Troubleshooting & FAQ
What if my original skeg is heavily damaged or broken off?
This skeg guard is also a repair solution. It can be installed on a broken skeg as long as at least 2-3 inches of the upper skeg remain for the guard to mount securely to. File any rough edges smooth before installation.
How do I prevent the mounting bolts from coming loose?
We include a packet of Loctite 262, a high-strength thread locker. A small drop on the threads of each bolt before tightening will secure them against engine vibration. This step is critical for a safe, long-lasting installation.
Is the mirror finish just for looks?
While the polished mirror finish looks great, its primary purpose is to provide a smooth surface that reduces drag and resists marine growth and corrosion, adding to the longevity of the 316 stainless steel.
kind_of_driveCan I install this myself, or do I need a mechanic?
This skeg guard is designed for easy, DIY installation that takes about 5 minutes. The kit includes all necessary hardware, a hex key, and instructions. You will only need a drill with a 1/4" bit and a mallet.
