Product Details

The Sierra 18-2747 is a replacement drive bellows assembly designed for MerCruiser Alpha One Generation II stern drives manufactured from 1991 and newer. This critical component creates a watertight seal between the transom assembly and the stern drive, protecting the U-joint bellows area from water intrusion while allowing the drive unit to pivot and articulate.

Key Features:

  • Premium black rubber construction for durability and flexibility
  • Direct replacement for MerCruiser part number 55-2691 and Mercury part number 816431
  • Complete kit includes bellows, bellow flange ring, hose clamp, and ground clip
  • Precision-molded design ensures proper fit and reliable sealing
  • Compatible with all 1991 and newer Alpha One Gen II applications

This bellows assembly is essential for preventing water from entering the boat through the stern drive opening. Regular inspection and replacement of drive bellows is critical maintenance, as a torn or deteriorated bellows can lead to catastrophic water damage. Sierra Marine parts are manufactured to meet or exceed OEM specifications, providing reliable performance at a competitive value.
