Troubleshooting & FAQ
How do I know if my bell housing gasket is failing?
Possible signs include water in the gimbal bellows, milky or water-contaminated drive oil, or visible corrosion and leakage near the bell housing and gimbal housing connection.
Will this kit fit a MerCruiser Alpha drive?
No. This listing is for the MerCruiser Bravo applications shown above and should not be used for Alpha models unless the applicable service documentation confirms the same reference number and fitment.
Is sealant needed with these gaskets?
Do not add sealant unless the applicable service manual specifically calls for it. Follow the installation requirements for your exact drive model.
When should this kit be replaced?
Replacement is generally appropriate whenever the sterndrive is removed for service or when the gasket or O-rings show wear, damage, hardening, corrosion, or leakage. There is no fixed time-based replacement interval stated for this kit.

No. This is an aftermarket replacement kit intended for the listed applications and reference numbers.
