Mercury U-Joint / Cardan Joint (864281A2)

The Mercury U-Joint / Cardan Joint (864281A2) is a genuine Mercury spare part for Mercury marine engines and sterndrive drive systems, enabling the lossless transmission of engine power through angular movements. In Mercury drive systems, the U-joint (cardan joint) creates a flexible and balanced connection between the engine and the drive shaft, reducing vibration and increasing ride comfort and control. Thanks to its robust construction, it offers reliable power transmission even under high torque.

U-joints operating in marine environments are subjected to challenging conditions such as constant rotation, angle variations, load fluctuations, and humidity. A worn or playful U-joint can cause vibration, increased noise, and, in later stages, serious drive system damage. The Mercury U-Joint / Cardan Joint (864281A2) provides long-lasting use and maintains system alignment with its durable metal alloys and precisely machined connection surfaces.

Mercury U-Joint / Drive Joint Specifications

The Mercury U-joint, code 864281A2, is compatible with many Mercury and MerCruiser sterndrive applications. When used with correct installation and periodic maintenance, it increases power transmission efficiency, minimizes vibration, and provides a quieter ride. Using genuine Mercury universal joints during maintenance and repair supports the drive system operating near its factory-standard performance and reduces maintenance costs in the long run.
