Maintain proper sealing and protection of the sterndrive transom assembly with the Mercury MerCruiser Bellows Assembly 36222A2. This genuine Mercury Marine OEM bellows assembly was designed to provide a flexible watertight seal between the sterndrive and transom assembly, protecting critical drivetrain components from water intrusion.
This component is designed exclusively for early, vintage sterndrive configurations:
- Target Models: MerCruiser I, IA, IB, IC, and EZ-Shift outdrives
- Production Era: Vintage models built between 1963 and 1966
The bellows acts as a protective rubber sleeve around the driveline area, allowing the sterndrive to move during steering and trimming while keeping water out of the drive shaft housing. Proper bellows condition is critical because failure can allow water to enter the gimbal housing and damage internal components such as the gimbal bearing or U-joints.
Note: This part number is NLA (No Longer Available) from Mercury Marine, meaning it has been discontinued and may only be found as remaining dealer inventory or new-old-stock.

Replacing worn or cracked bellows helps:
- Prevent water from entering the transom assembly
- Protect U-joints and gimbal bearings from corrosion
- Maintain proper sterndrive reliability
- Avoid costly drivetrain repairs
