Are those fish boxes under the seats? I would be pulling that fuel tank and checking it for corrosion and to see whats happening under it. Also check to see if there are routes beside or around the foam for water to flow back to the bildge. If not then you need to make some. There was a couple of really good threads on the Hewescraft forum about this.
Good luck with her FB. I will be paying attention to this one for sure.
