What components are included in the transom kit?

The kit supplies the complete hardware needed for a typical transom bellows replacement, letting you avoid piecemeal shopping and reducing installation time. Components are selected to match the layout of Bravo-style drives so you can rebuild the exhaust, shift coupling and gimbal seal areas in one service session.

How does replacing the bellows and gimbal bearing help the boat?

New bellows and a fresh gimbal bearing restore the drive’s sealing and support functions, lowering the risk of stern leaks and misalignment that can damage the outdrive. A properly sealed transom prevents water ingress while the bearing maintains correct drive angle and reduces vibration.

• Prevents water entry through worn or cracked bellows

• Includes clamps and gaskets for a complete, sealed installation

Yes — the GHmarine kit is made as a repair equivalent to several OEM numbers and aftermarket references, letting it serve as a direct replacement in many service situations. Check the part identifiers on your current components to ensure a match before installation.

• Interchanges with MerCruiser, Sierra and Mallory reference numbers
• Useful when OEM originals are out of stock or obsolete
• Includes all primary sealing and mounting parts for straightforward swap-out
