- Description
The MARTYR Mercury Anti-Ventilation Anode (Aluminium) – 8M0137814A is a premium sacrificial anode designed to protect Mercury outboard engines (175–300 HP range) from galvanic corrosion. It is engineered as a direct OEM replacement for Mercury part number 8M0137814, ensuring precise fitment and reliable performance.
Installed on the anti-ventilation plate (cavitation plate) of the gearcase, this anode provides targeted protection to critical components such as the lower unit, propeller hub, and surrounding metal surfaces.
Manufactured from high-purity aluminum alloy, it delivers longer lifespan and improved efficiency compared to traditional zinc anodes, making it ideal for saltwater and brackish environments.
