Re: I did a solar thing.....
Was looking at your setup to flag for you.
With an aluminum boat ( like my own) you have to make sure there are zincs in the water. O/B with a zinc or drop over the side type sacrificial zinc.
With dissimilar metals you get migration from one metal to the other metal. Electric current accelerates that. Meaning metal gets eaten away while in the water. Fine for the zincs- it's their job. Catastrophic for the boat as its slowly eaten away.
Of course while out of the water is not a problem
