Installation Guide

Installation is straightforward, requires no marine technician, and can be completed in minutes. Follow these general steps:

1. Ensure there is at least 2 to 3 inches of the upper skeg remaining to securely hold the guard.
2. Clean the surface of your existing skeg to ensure it is free of debris.
3. Using a mallet, gently tap the guard over your current skeg until fully seated.

6. Tighten the bolts securely with the provided Allen wrenches until the guard is firmly in place.

Troubleshooting & FAQ

How do I know if this will fit my engine?
Please carefully review the "Compatible Engine Models" table above. If you are unsure, compare the dimensions and visual shape of your lower unit with our product images.

Can I install it on an already broken skeg?
Yes, the guard can be installed over a broken skeg as long as there is at least 2 to 3 inches of the original skeg remaining to secure the mounting hardware.

What is the benefit of the drain hole in the design?
The drain hole is a critical feature that allows water to escape from inside the guard. This prevents water from becoming trapped, which stops corrosion and protects the skeg from damage caused by freezing in cold climates.
