Anoda vnitřního bloku válců pro vnější motor Yamaha 25-90HP (688-11325-00)
Internal Cylinder anode for Yamaha
Fits the following Yamaha outboard models -
Two-Stroke:
25Q,
40H,
40N,
40V,
50D,
50H,
80A,
85A,
90A
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.
