Product Details

The Sierra 18-6401 is a premium universal joint (U-joint) assembly engineered for MerCruiser Bravo stern drive systems. This critical drivetrain component ensures smooth power transfer from the engine to the propeller, providing reliable performance for your marine vessel.

Key Features:

  • Direct replacement yoke assembly for MerCruiser Bravo I, II, and III stern drives
  • Fits models from 1998-2005 with serial numbers 0B664190 and up (serial range 0B664190-0M111207)
  • GKN-style design utilizes external clips for secure u-joint retention
  • Replaces Mercury Marine part numbers 864244A2, 12784A10, and 12784A4
  • Cross-references with GLM part number 28060
  • Also compatible with MerCruiser Blackhawk drives (1993-1998)

This assembly serves as the replacement for the original Bravo Meritor assembly, with the key difference being the clip design—the Meritor version uses internal clips while this GKN-style uses external clips. Built to OEM specifications, the Sierra 18-6401 delivers the durability and precision required for demanding marine applications.
