Okay - Now that I have my re-wiring taken care of, what is the most effective way to deal with Galvanic Corrosion, or better yet prevent it. During my boat's survey, galvanic corrosion was determined to be slight if any, and I would prefer to keep it that way. Current Configuration: Prop and brace are all copper and all the same color (after scraping) Boat has two batteries, one aft starter and one forward dual purpose. All battery wiring is in good shape. Batteries are swithced though a Guest four position switch (1,2,both,off). Powerplant is an Atomic 4. Any suggestions? I have heard of zincs and understand their role, but am unsure if they are on the boat, or if so where. If they aren't there, is there a good kit available for installation? Thanks - Rob
