Workshop sequence
General workshop guidance only; use the service procedure for your exact drive or engine configuration.
- Confirm that the part being replaced is the bell-housing exhaust bellows rather than the U-joint bellows, and compare the existing part against reference 18654A1.
- Clean and inspect the bell-housing and transom-side mounting necks so both seating surfaces are free of old material, corrosion, or debris before fitting the new bellows.
- Position the bellows without twists or uneven folds and secure both ends with the hose clamps in accordance with the MerCruiser service manual for your specific drive.
