Alpha One Gen II U-Joint Yoke Assembly (864281A2)

Alpha One Gen II U-Joint Yoke Assembly

The Alpha One Gen II U-Joint Yoke Assembly is a vital driveline component designed to deliver smooth, consistent power from your engine to your sterndrive. Specifically built for MerCruiser Alpha One Gen II drives, this yoke assembly ensures proper alignment and strength under load—keeping your boat running strong and vibration-free.

Built for Smooth Power Transfer

The U-joint yoke plays a key role in your boat’s propulsion system. It connects the engine coupler to the input shaft of the drive, allowing for flexible rotation and angle changes. This results in smooth power delivery through the driveline—even during aggressive throttle or tight turns.

Durable, Marine-Grade Construction

Manufactured from high-strength, corrosion-resistant materials, this assembly is built to handle constant torque, motion, and harsh marine conditions. Whether you’re cruising in saltwater or freshwater, it stands up to wear and reduces the risk of premature failure.

Perfect Fit for Alpha One Gen II Drives

Engineered to match OEM specs, the Alpha Gen II U-joint yoke assembly installs directly with no modifications required. It’s compatible with most MerCruiser 4-cylinder, V6, and small-block V8 engines running the Alpha Gen II sterndrive.

Reduces Vibration and Wear

When your yoke assembly is worn or out of balance, you’ll feel it—often through vibration, clunking, or uneven engine load. Replacing it restores proper alignment and eliminates stress on other components like the gimbal bearing, input shaft, and universal joints.

Easy Installation for DIY or Professional Service

This assembly is designed for easy installation with basic marine tools. Whether you’re doing a full driveline service or just replacing worn components, the Alpha One Gen II U-Joint Yoke Assembly helps restore reliability and confidence on the water.
