Installation Guide
-
Ensure proper fit before installing. There must be at least two to three inches of the original upper skeg remaining to securely attach the new Skeg Guard.
-
Prepare the surface by filing any spurs or jagged edges smooth. This allows the Skeg Guard to slide easily over the existing skeg.
-
Position the guard on the skeg. Use a leather, rubber, or wooden mallet to gently tap it until it is fully seated.
-
Drill mounting holes using the pre-drilled holes in the Skeg Guard as a guide. A 1/4" drill bit is required.
-
Install the hardware using the stainless steel screws, nuts, and hex key tool supplied with the product to secure the guard.
Troubleshooting & FAQ
How do I confirm this skeg guard fits my engine?
This guard is designed for Mercury/Mariner 40, 50, and 60 HP 2 & 4-Stroke outboards from 1991 to present. The most critical factor is the gearcase size; this part fits the smaller 3.44" gearcase. Please measure your gearcase or verify your part number (27341) to ensure compatibility.
The fitment years seem to conflict across different websites. Which is correct?
While some sources state a narrower year range (e.g., 2003-2015), our data and multiple suppliers confirm fitment from 1991 to present for models with the 3.44-inch gearcase. Always prioritize the gearcase measurement and visual comparison over the year range alone.
What is required for installation?
The kit is a bolt-on design and includes the necessary mounting hardware and a drill bit. You will need to drill two holes through your existing skeg. Ensure at least 2-3 inches of the upper skeg is intact to provide a solid mounting surface.
