Product Details

The Quicksilver 865425A03 U-Joint Assembly is a genuine OEM GKN-style universal joint assembly designed for MerCruiser Bravo X, Bravo XR, and Bravo XZ sterndrive systems. This assembly serves as the critical rotating connection between the engine and the sterndrive unit, transferring power from the transmission to the drive while accommodating the angular movement of the outdrive during steering and trim adjustments.

As a factory-authorized Quicksilver component manufactured by Mercury Marine, this U-joint assembly meets the same stringent specifications as the part originally installed in your MerCruiser sterndrive system, ensuring proper fitment, durability, and reliable performance on the water.

Key Features:

  • Genuine OEM Quicksilver/Mercury Marine factory part — not aftermarket
  • GKN-style universal joint assembly construction
  • Designed for high-torque MerCruiser Bravo series sterndrive applications
  • Direct replacement for Mercury/MerCruiser U-joint assemblies on Bravo X, XR, and XZ drives
  • Sold as a single complete assembly
  • Backed by Mercury Marine's 1-year factory warranty against defects in materials and workmanship

This U-joint assembly is a critical drivetrain component in MerCruiser Bravo stern drive systems. Replacing a worn or damaged U-joint assembly restores smooth, efficient power transfer and helps prevent catastrophic drivetrain failure. Always confirm fitment using your MerCruiser serial number prior to ordering.
