Tecnoseal R5MG Rudder Anode - Magnesium - 5" Diameter

The Tecnoseal R5MG Rudder Anode in magnesium is essential cathodic protection for any serious boater or angler who relies on their vessel's steering system. This 5-inch diameter magnesium anode sacrifices itself to protect your rudder from galvanic corrosion, extending component life and ensuring responsive, reliable steering in both saltwater and freshwater environments.

Magnesium anodes work through galvanic protection by becoming the sacrificial metal in the electrochemical corrosion process. Because magnesium is more electronegative than steel rudder components, it corrodes preferentially, preventing rust and pitting on your rudder itself. The Tecnoseal R5MG provides substantial protection while maintaining minimal weight impact on vessel balance and performance.

Whether you fish offshore, cruise coastal waters, or maintain a recreational fishing boat, the Tecnoseal R5MG Rudder Anode is a cost-effective maintenance investment that prevents expensive rudder replacement or repair. Experienced captains understand that replacing a corroded rudder can cost thousands and sideline your boat during critical fishing or boating season.
