Product Details
This U-Joint Bellows Kit serves as a direct replacement for Volvo Penta sterndrive models (SX and DP series, 1994–Present) and OMC Cobra clutch dog models (1986–1993).

- Installs on the transom shield assembly to protect the U-joint.
- Made from a high-grade marine rubber compound for durability.
- Accordion-style design allows for sterndrive movement while maintaining a water-tight seal.

Troubleshooting & FAQ
How do I know if this bellows will fit my sterndrive?
This kit is designed for Volvo Penta SX and DP series drives from 1994 to present, and OMC Cobra clutch dog models from 1986–1993. The best way to confirm is to check your model against the compatibility table and cross-reference your existing part number with our Part Number Matrix.
What are the signs that my current U-joint bellows is failing?
Common signs of a failing bellows include visible cracks, splits, or perishing of the rubber. You may also find water inside the boat near the transom assembly after use, which indicates a leak. Any water intrusion risks catastrophic damage to the U-joint and gimbal bearing.
How often should the U-joint bellows be replaced?
As a preventative maintenance item, most manufacturers recommend inspecting bellows annually and replacing them every 3-5 years, depending on usage (saltwater vs. freshwater) and environmental exposure. It is often replaced along with the gimbal bearing and shift cable bellows.
Is this a complete kit for the job?
This kit includes the U-joint bellows and the necessary stainless steel clamp for one side of the installation. Depending on your model, you may need a second clamp or special tools, which are not included.
