MerCruiser Mercathode Controller

MerCruiser Mercathode Controller – Precision Corrosion Control for Sterndrives

The MerCruiser Mercathode Controller is a key component in Mercury Marine’s advanced corrosion protection system, specifically designed to safeguard your MerCruiser sterndrive from the harmful effects of galvanic corrosion. Ideal for both saltwater and brackish water environments, this controller regulates the electrical current sent to the anode system, offering consistent and automatic protection to metal components below the waterline.

Engineered to meet Mercury’s high OEM standards, the Mercathode Controller operates by sensing voltage differences caused by dissimilar metals submerged in water. It then delivers a controlled, low-voltage current to counteract the electrochemical process of corrosion. This intelligent system allows the Mercathode to adapt in real-time, ensuring optimal protection under varying water and environmental conditions.

Compatible with most MerCruiser Alpha and Bravo series drives, this controller is easy to install or replace, making it perfect for routine upgrades or system repairs. It draws minimal power from the boat’s battery and works seamlessly with the rest of the Mercathode system, including the anode assembly and wiring harness.

The controller is housed in a rugged, waterproof casing, built to withstand harsh marine conditions for long-term reliability. It’s an ideal solution for aluminum and steel hulls, or for any boat that features a combination of underwater metals.

By actively preventing galvanic corrosion, the Mercathode Controller not only extends the lifespan of your drive and other underwater components but also maintains performance and efficiency. For maximum protection, pair it with Mercury’s genuine anodes and regularly inspect your system as part of your boat’s maintenance routine.

Whether you’re cruising, fishing, or moored at the dock, the MerCruiser Mercathode Controller offers unmatched peace of mind—ensuring your boat stays protected and ready for the water.
