Workshop sequence
General workshop guidance only; use the service procedure for your exact drive or engine configuration.
- Compare the removed bellows against the replacement part and reference numbers, and verify whether your installation requires separate clamps, retaining rings, or sleeves.
- Clean and inspect the gimbal housing and bell housing mounting flanges so the sealing lands are free of old adhesive, corrosion, and debris.
- Fit the U-joint bellows in the orientation specified by the MerCruiser service manual for your Bravo, Blackhawk, or Vazer drive, ensuring the folds are seated evenly without twisting.
- Secure the bellows connections and check clearance through the full trim and steering range before returning the boat to service.
