Tecnoseal R7 Rudder Anode - Zinc - 6-1/2" Diameter

The Tecnoseal R7 Rudder Anode in zinc is designed for effective cathodic protection in marine propulsion and steering systems that are exposed to various water environments, including saltwater, brackish, and freshwater. This product is essential for boaters who want to prevent galvanic corrosion that can damage underwater metals, particularly rudders and trim tabs.

Engineered to corrode preferentially, the 6-1/2-inch diameter zinc anode draws corrosion away from steel and aluminum components, thereby extending the lifespan of critical steering apparatus. Weighing 8.8 lbs, this anode is made of pure zinc, ensuring robust galvanic protection through direct contact with the rudder shaft or blade assembly.

Ideal for inboard cruisers, fishing vessels, and commercial operators, the Tecnoseal R7 Rudder Anode is compatible with any boat using a conventional through-hull rudder system in corrosive waters. Its compact profile of 7 x 3 x 7 inches allows for easy retrofit installations while maintaining sufficient surface area for reliable cathodic protection.
