Mercury Inner Transom Plate (8M0138839)

The Mercury Transom Plate Inner (8M0138839) is an original Mercury replacement part that forms the inner section of the connection structure between the engine and the hull in Mercury sterndrive systems. In Mercury transom systems, the inner transom plate ensures the balanced transfer of load to the hull, maintains secure connection points, and preserves system integrity. Correct alignment and robustness are critical for driving safety and long-term durability.

In a marine environment, the transom area is constantly exposed to loads, vibrations, humidity, and saltwater. An inner transom plate that has deformed or corroded over time can lead to misalignment, sealing problems, and eventually serious structural damage. The Mercury Inner Transom Plate (8M0138839) minimizes these risks thanks to its robust metal construction and original dimensional tolerances, providing a reliable foundation for hull connection.
