Re: zincs
Hi, Sacrificial Zincs are designed to corrode due to electrolosis. If they are corroding at a rapid rate, which it sounds like. This indicates an electric current in or around the boat. Start checking bonding wires, grounding wires, and cable connections. Sometimes even a small problem can cause a zinc to erode quickly. If there are boats near yours, check with the owner and see if he is experiencing the same problem. If he is, it could be something in the water. If not, it could be isolated to your boat. I had a guy with similar problem, after checking everything on his boat, he asked the guys on each side at his dock. They were having the same problem. They later found a shore power wire under the dock with a slice in the insulation. Repaired the wire and the problem went away. Sometimes it not easy to find.
