Troubleshooting & FAQ
How do I know if this bellows fits my specific boat?
This kit is designed for a broad range of Volvo Penta stern drives from 1975 to present. The best way to confirm fitment is to check your model against the compatibility table on this page. If your model is listed, it will fit. Also, verify that your existing part number matches one of the numbers in the Part Number Matrix.
What are the signs of a failing U-joint bellows?
The most common signs of failure are visible cracks, splits, or perishing of the rubber. Another critical sign is finding water inside the bellows during a service inspection, which indicates a leak. You may also hear grinding or whining noises from the U-joint area, indicating water has already caused damage.
How often should this bellows be replaced?
It is recommended to inspect the U-joint bellows annually and replace it as part of a regular stern drive service schedule, typically every 1-2 seasons, depending on usage and water conditions (saltwater vs. freshwater). Proactive replacement prevents catastrophic U-joint failure.
