Installation Notes

Disconnect the battery and adhere to all manufacturer safety protocols before starting.
Separate the sterndrive from the bell housing as detailed in your MerCruiser service manual.
Carefully remove the old gasket and o-rings. Thoroughly clean all mating surfaces to remove old material and corrosion.
Install the new gasket and o-rings from the kit onto the bell housing. Ensure they are seated correctly.
Reassemble the sterndrive to the bell housing, ensuring correct alignment. Torque all fasteners to the manufacturer's specified values.
After reassembly, inspect for any leaks around the sealed area before operation.

Troubleshooting & FAQ

How do I know if my bell housing gasket is failing?

Common signs include water in the gimbal bellows, milky or water-contaminated drive oil, or visible corrosion around the area where the bell housing and gimbal housing meet.

Will this kit fit a MerCruiser Alpha drive?

No, this gasket kit is specifically for MerCruiser Bravo I, II, and III series sterndrives. It is not compatible with Alpha models.

Is any sealant needed with these gaskets?

Generally, no additional sealant is needed. The components are designed to create a positive seal on their own. Always consult your specific service manual for any exceptions or additional steps.

What is the replacement interval for this kit?

It is best practice to replace these seals and O-rings whenever the sterndrive is removed from the bell housing for service. There is no fixed time-based interval; replacement is condition-based.
