Hi All, I am wondering how long you found your mercathode to last. I hear people say they found their mercathode was not working (don't bo how common this is) and wondering if their is a time fram that they should be replaced. I ask becuse once the boat is in the water the cost of haul out is probably more then it would cost to have my marina install a new mercathode reference anode. And unfortenetly ther is no way to test on the hard.
