Ok, we sail the Periwinkle from fresh water to salt water for the summer and then back to salt. Consequently I want to use aluminum anodes due to the coating that is produced on zinc anodes with this type of operation. I also know the all need to be the same. But, what about engine anodes and the plate located on bottom of vessel? Is it an anode? It shows no degeneration. Is that a zinc anode that isn't working or a ground. If it is an anode can I get it in aluminum? If so where?
