Technical Specifications

Package Contents

• 1 x Skeg Guard (27211)
• 1 x Drill Bit (1/4-inch)
• 2 x Nuts
• 2 x Hex Wrenches
• 4 x Screws
• 1 x Threadlocker Sealant

Installation Guide

This is a bolt-on kit that requires drilling. Important: You must have at least 2-3 inches of the original skeg remaining for a secure installation.

1. Clean the remaining skeg area thoroughly to remove any marine growth or debris.
2. Test fit the skeg guard over the damaged skeg to confirm alignment.
3. Mark the two drill-hole locations on the skeg using the guard as a template.
4. Use the included 1/4-inch drill bit to carefully drill through the skeg at the marked spots.
5. Apply the supplied threadlocker sealant to the threads of the mounting screws. This step is critical to prevent the hardware from loosening due to engine vibration.
6. Position the skeg guard and insert the mounting screws.
7. Secure the hardware using the included nuts and hex wrenches. Tighten until snug but do not overtighten.
8. Allow the threadlocker to cure for the recommended time before operating the vessel.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
A: This skeg guard fits a wide range of Mercury/Mariner outboards from 75-300 HP (1999-Present). Please check the "Compatible Engine Models" table and use our Mercury Serial Number Guide to verify your specific model and year before ordering.

Q: How much of my old skeg needs to be left for this to work?
A: You must have at least 2-3 inches of the original skeg remaining to ensure a secure and stable installation. If your skeg is broken off higher than that, this product will not mount correctly.

Q: What's the purpose of the drain hole on the bottom?
A: The drain hole is a key feature that prevents water, sand, and other debris from accumulating inside the guard. This reduces the risk of corrosion and avoids trapping excess weight on the lower unit.
