Tecnoseal R3MG Rudder Anode - Magnesium - 3-3/4" Diameter

The Tecnoseal R3MG Rudder Anode is a magnesium sacrificial anode designed to protect your boat's rudder assembly from galvanic corrosion in saltwater and brackish environments. This anode is essential for serious boaters who understand the importance of preventing metal degradation that can occur beneath the surface of the water. With a diameter of 3-3/4", it is specifically engineered to fit standard rudder tube installations commonly found in various types of boats.

Constructed from magnesium, the R3MG offers superior electrochemical potential compared to zinc, making it the preferred choice for freshwater and slightly brackish conditions. This anode is designed to corrode preferentially, effectively drawing destructive electrolytic attacks away from your rudder's structural components. As the anode wears away over time, it continues to provide protection against pitting and structural weakening, ensuring reliable handling and safety.

Boaters, including anglers and cruising captains, should inspect and replace their rudder anodes annually or more frequently during high-use seasons. The Tecnoseal R3MG can be easily threaded or fastened directly to the rudder tube, making installation straightforward. This product is an essential investment for maintaining the integrity of your boat's steering system and prolonging its lifespan.
