I have a 28' trailer trawler which spends most of it's time on it's trailer. Zincs are readily accessible. Does anyone clean their zincs to expose clean metal? Good/bad, waste of time?
The diver’s zinc was at least 10 years old..... still almost all there.
Any anode that lasts that long is an anode that is not doing its job.
Agreed. Something wrong there. Unless in fresh water. Even then my hull zinc went to 50% in three years of mainly fresh water.
