Engineered Marine Products Heavy Duty U-Joint 94-00801, Replaces 75832, Fits Alpha One & TR/TRS Units

The Engineered Marine Products 94-00801 is a heavy duty U-joint built to handle the torque and shock loads of a marine stern drive coupling. It is machined for a precise fit and includes both a straight and a 90 degree grease fitting, so it can be serviced with a standard grease gun regardless of how the drive is oriented in the boat. This U-joint is designed as a direct replacement for worn or failed factory joints on #1 and Alpha One drive units within serial number range 1684188-B418818, as well as TR/TRS and II SSM units.

A U-joint transmits rotational power through an angle, and in a stern drive it is the critical link that lets the drive tilt and trim while still delivering engine power to the propeller shaft. Because this component takes constant load and vibration, Engineered Marine Products manufactures the 94-00801 to heavy duty specifications rather than a lighter passenger-vehicle-style joint. It is a common maintenance and rebuild item for boat owners servicing their drive coupler or replacing a joint showing wear, looseness, or corrosion.
