T&T: Fresh water anodes

[Chuck and Susan]

Andrew, You should change your zincs to either magnesium or aluminum anodes sine zinc will develop a coating in fresh water and stop protecting the boat and anything connected to that zinc. To much potential for expensive damage to do a half a___d job. Aluminum is a good all around anode since it will work in fresh, brackish and salt water. Any marina with a lift can do a quick haul and change the zincs under water in a very short time. Chuck
