Water leaks into the transom assembly

Increased risk of gimbal bearing damage

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