Function

The exhaust bellows connects the engine exhaust outlet to the sterndrive exhaust passage while allowing the drive to move during trimming and steering. This flexible rubber component helps:

• Maintain a sealed exhaust passage

• Prevent water intrusion into the boat

• Allow movement of the sterndrive and engine assembly

The bellows is secured at each end with stainless steel hose clamps to maintain a tight, corrosion-resistant seal.

Service Notes

A worn or damaged bellows may cause:

• Water leaks into the transom assembly

• Increased risk of gimbal bearing damage

• Exhaust leaks or reduced exhaust efficiency

Bellows should be inspected regularly and typically replaced during sterndrive service intervals.

Fitment Tip:
Always verify compatibility using the sterndrive model and serial number. MerCruiser sterndrives use several types of bellows (exhaust, U-joint, and shift cable), and the correct part depends on the drive model and installation configuration.
