Troubleshooting & FAQ

Will this fit my specific Mercruiser engine?

This skeg guard is designed specifically for Mercruiser Bravo I and Bravo III drive units manufactured from 1990 to the present. Please verify your drive model and year before ordering.

Do I need to drill holes to install this?

Yes, installation requires drilling two holes into your skeg. The kit includes all necessary mounting hardware, a drill bit, and detailed instructions to guide you.

What is the purpose of the drain hole?

The drain hole at the bottom allows water to escape easily. This prevents water from getting trapped, which can lead to corrosion or damage from freezing in cold climates.

How does this repair a damaged skeg?

The guard fits securely over your existing skeg, covering chips, cracks, or small missing pieces. It restores the skeg's original hydrodynamic profile, improving handling and protecting it from further damage.
