Engineered Marine Products 91-91007 Gimbal Bearing Installer Puller and Alignment Tool

The Engineered Marine Products (EMP) 91-91007 is a professional-grade gimbal bearing installer, puller, and alignment tool designed for sterndrive marine engine service. This all-in-one tool handles the full scope of gimbal bearing maintenance — removing the old bearing, installing the new one, and verifying proper drive shaft alignment — without the need for multiple separate tools.

The gimbal bearing sits between the transom and the sterndrive unit, supporting the U-joint shaft under constant rotational load. Proper removal, installation, and alignment of this bearing is critical to preventing premature wear on the bearing, drive, and engine coupler. The EMP 91-91007 is engineered to make this job accurate and efficient for both marine professionals and experienced DIY boaters.
