After 2 weeks in the water my shiny new prop cone zincs are both heavily pitted with craters and flaking corrosion. I couldn't see the other zincs. The port cone is very uniformly rough all around with none of the original surface left. The starboard cone looks quite different with craters that are in patches with some of the original surface left. I assume this is not normal. What could be causing this? Mercathode problem, stray current?
I'm having the dealer check it out. They asked if there were any old boats within 100 feet of mine that could be dumping current into the water. How the heck do you answer that one?
If it is a problem with the marina, will keeping myself disconnected from shore power prevent the problem?
