Aluminium Anode for Johnson-Evinrude Gearcase Anode for J/E 50HP-140HP Reference to: 393023, 436745 The anode is made from a metal alloy with a more ""active"" voltage (more negative electrochemical potential) than the metal of the structure it is protecting (the cathode). The difference in potential between the two metals means the sacrificial anode material corrodes in preference to the structure.
