[QUOTE="PSG-1, post: 384978, member: 6937"] I did some reading, and you're right....it is possible to 'overprotect' an aluminum boat by using magnesium anodes in salt water. Says the voltage difference can actually start lifting paint. :shock: Guess I should have studied into that before deciding to slap a Mg anode on my boat. #-o My boat has been back in the water for about 60 days. Perhaps I should haul it out ASAP, and check condition of the hull, and replace the anode with one made of aluminum, which is less reactive than magnesium, but more reactive than zinc. [/QUOTE]
