Alumacraft 175 Pro - If a mod sees this please update the thread title.
I found my leak, and it is much worse then expected. I wish I would have crawled around under the boat before I redid every bolt, thru hull, pump and plumbing connection on the boat.
It looks like it cracked right on welds for the internal structure, I can see all the welds looking up and down the hull and these have paint flaking away and a visible crack, what looks like a smudge running down the hull appears to be a mineral trail left by our hard water as it runs down the boat and drips off or dries.
