Product Details

The Sierra 18-9218 U-Joint Assembly is a precision-engineered replacement universal joint designed for Mercruiser stern drive applications. This critical drivetrain component connects the gimbal housing to the drive shaft, transferring power from the engine to the propeller while accommodating the steering and trim movements of the outdrive.

Key Features:

  • Direct replacement for Mercruiser OEM part numbers, ensuring proper fit and function
  • Manufactured to meet or exceed OEM specifications for durability and performance
  • Precision-machined components for smooth operation and long service life
  • Corrosion-resistant materials designed for harsh marine environments
  • Includes bearings and hardware required for installation

Regular inspection and replacement of U-joints is essential for maintaining optimal drivetrain performance and preventing costly damage to other stern drive components. Sierra International is a trusted name in marine replacement parts, offering OEM-quality components at competitive prices.

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Fast order

the amazon payment did not work; hope I don't get double billed since I went with paypal afterwards. Meanwhile, I could not verify that my amazon order is cancelled/never placed.

Super fast shipping well informed will order again

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
