Aluminum Anode Transom Bar For BRP OMC-Johnson Evinrude 5007089
Tax included.
Aluminum Anode For Johnson Evinrude
Stern bracket aluminium anode for J/E 60HP-300HP
Reference to: 5007089
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.
