whichwaysup Posted May 17, 2021 Report Share Posted May 17, 2021 So, apparently my son inherited the "dumb" gene from me that causes otherwise sensible men to buy boats into which they can continually hurl money. He and his buddy spent a good portion of their hard earned money on a little G3 aluminum boat. It's a great boat and a GREAT engine, but it's been the victim of electrolysis/galvanic corrosion, or whatever demons cause pinholes in aluminum boats. While the boat has a lot of them (bad), they are all still very very small (good) and they are confident that with enough JB weld, they can probably make it halfway to any desired fishing destination. They seem less concerned about that prospect than I do, but what do I know, I recently went through a 2 year process of buying my boat twice. All teasing aside, I do believe that they can correct the problems that have already happened. The question for this group is - does anyone know what can be done to stop or at least slow the process that is causing this in the first place? They are already going to replace the bunk carpet with plastic skids to keep that water away from the boat when it is on the trailer. I've also got them removing every piece of metal from the hull that is not aluminum so we can put a sealant between the two metals. I've read that you can mount zinc anodes to the hull, and they are looking into that. Also, we'll be checking what little wiring there is to make sure we don't have any stray current. Aside from completely re-sealing the bottom of the boat (which will probably happen in the future) anything else we are missing? This hole "pinhole" thing with aluminum is a terrifying mystery to me. At least with Fiberglass, you can always sand it down and re-apply it! Quote Link to comment Share on other sites More sharing options...
