Troubleshooting & FAQ
Will this fit if my skeg is already broken?
Yes, this skeg guard is designed to be installed on damaged skegs. You need at least 2–3 inches of the original skeg remaining to ensure a secure mounting point.
What tools are required for installation?
The package includes a drill bit, screws, nuts, and hex wrenches. You will need a power drill and are advised to use a marine-grade sealant (not included) for a fully waterproof installation.
How does the built-in drain hole work?
The drain hole prevents water from getting trapped inside the guard, reducing the risk of corrosion and damage to your lower unit by allowing it to drain out when the boat is on a trailer or lift.
Is the stainless steel finish durable enough for saltwater?
Yes, it is constructed from marine-grade 316 stainless steel, which offers superior resistance to corrosion and abrasion in both freshwater and saltwater environments.
