Osculati 43.640.17 – Mercury 8239121 & Suzuki 55321-94900 & Evinrude 5034616 Magnesium Anode Rod
The Osculati 43.640.17 magnesium anode rod is purpose-built for internal engine corrosion control in freshwater applications. Compatible with Mercury (8239121), Suzuki (55321-94900), Evinrude/Johnson (5034616 / 5030907), OMC, and Tohatsu engines, this rod-style anode threads directly into internal cooling passages. Magnesium’s high electrochemical potential makes it ideal for low-conductivity water, delivering rapid and effective galvanic protection where zinc or aluminium are less reactive.
