Re: Saltwater and Aluminum(?) boats??
Living on the Gulf Coast I can tell you that I have seen 1000s of aluminum boats on the water. And, I'm sure they all leak a little, just like those boats that are fresh water only. I will say this, salt will collect in every nook and cranny without question, and salt water will corrode aluminum over time. It won't be the old reddish rust, it will be the pitting and discoloration that is a little harder see at first. Electrolysis happens when two dis-similar metals are in contact with each other or when there is a grounding problem on the boat. That said, I don't think electroysis is as big a concern as simple salt corrosion. (In my opinion) Hopefully we can get a little more guidance from some of the saltier guys on here. I have similar questions about this topic. Perhaps using a small sacrificial anode on the boat (motor usually) will help to slow down the process?!?!
