Troubleshooting & FAQ
Will this fit my MerCruiser Bravo drive?
It is intended for MerCruiser Bravo 1 and Bravo 3 drives from 1990 to the present with the larger gearcase and oil recirculation system. It is not compatible with XR or SportMaster models. Approximately 2–3 inches of the original skeg must remain for installation.
How do I install the skeg guard?
Position the guard over the remaining skeg, use a rubber mallet carefully if needed for a snug fit, drill the mounting holes with the supplied drill bit, and tighten the included screws and nuts.
What is the purpose of the drain hole?
The drain hole allows water to escape from inside the guard, helping reduce water accumulation, corrosion, sediment buildup, and freeze-related damage.
What material is the guard made from?
The guard is made from mirror-polished marine-grade 316 stainless steel. Its lower wear tab is approximately 3 mm thick.

No. This is an aftermarket replacement intended for applications that reference MerCruiser 27051. Compare the drive configuration and the original part before installation.

Installation requires drilling the skeg and securely fastening the guard. If you are not comfortable performing this work, have the installation completed by a qualified marine technician.
