Troubleshooting & FAQ

Will this fit my MerCruiser Bravo drive?

It fits Bravo 1 and Bravo 3 models from 1990 to present with the larger gearcase and oil recirculation system. It is not compatible with XR or Sport Master models. A minimum of 2-3 inches of the original skeg is required for proper installation.

How do I install the skeg guard?

The kit is a bolt-on application. You will need to position the guard (using a rubber mallet if needed for a snug fit), drill holes using the provided drill bit, and then tighten the included screws and nuts.

What is the benefit of the drain hole?

The drain hole at the bottom prevents water from collecting inside the guard, which helps protect against corrosion, sediment buildup, and damage from freezing water.

Is this guard stronger than the original skeg?

It is constructed from marine-grade 316 stainless steel, offering excellent durability and corrosion resistance. The 3mm thick lower wear tab is designed to absorb impacts and protect the original skeg and propeller from damage.
