Installation Notes

  1. Position the sterndrive in the full-up position and remove the rear cover to access the drive components.
  2. Loosen and remove the old clamps securing the existing u-joint bellows.
  3. Carefully cut or slide the old bellows off the sterndrive and bell housing. Use of the OEM hinge pin removal tool (91-78310) will be necessary.
  4. Thoroughly clean the mounting surfaces on both the drive and housing, removing any old adhesive or debris.
  5. Apply a thin, even coat of a marine-grade bellows adhesive (not included) to both ends of the new bellows.
  6. Slide the new bellows into position and secure it tightly with the two included stainless steel clamps.
  7. Allow the adhesive to cure according to the manufacturer's instructions before reassembling the drive and aunching the vessel.

Troubleshooting & FAQ

How do I know if my U-joint bellows needs replacing?

Inspect your bellows regularly for cracks, splits, or brittleness. The most common sign of failure is water inside the bellows, often discovered during a service check. Any visible damage warrants immediate replacement to prevent catastrophic damage to the u-joints and gimbal bearing.

What happens if a U-joint bellows fails?

A failed bellows allows water to enter the sterndrive's gimbal housing, quickly destroying the gimbal bearing and u-joints. This can lead to a total loss of propulsion and costly repairs. Water intrusion is a critical failure that should be addressed immediately.

Is bellows adhesive necessary for installation?

Yes, using a quality marine bellows adhesive is highly recommended. It ensures a watertight seal between the bellows and the drive/housing, preventing leaks that can lead to premature part failure. Do not rely on clamping force alone.

What is the recommended replacement interval?

As a preventative maintenance item, most manufacturers recommend replacing all sterndrive bellows, including the u-joint bellows, every 3-5 years, depending on usage (saltwater vs. freshwater) and storage conditions.

Does this bellows fit my exact engine model?

This part is designed for specific MerCruiser drives made from 1967–1972 with serial numbers between 2062141 and 3472477. Always use the compatibility table and verify your serial number and year range before purchasing.
