I am in fresh water, Lake Michigan. The zincs on the exterior of my boat have never shown any wear. In 8 years I never checked the engine or transmission zincs.
The engine zincs were no doubt replaced with the engine rebuild but not the transmission.
Guess I better take a look, eh?

Zincs in fresh water are ineffective, that’s probably why yours haven’t shown any wear. You should be using magnesium or aluminum anodes.
Take a look back at post #3Zincs in fresh water are ineffective, that’s probably why yours haven’t shown any wear. You should be using magnesium or aluminum anodes.
+1 on that!They are properly anodes. Too many people refer to all anodes as zincs. That brings a lot of confusion into the discussion. If people would say anode or refer to them as aluminum anode, magnesium anode or zinc anode then there would be no confusion or at least less confusion.
