In my rebuild I went back with a slightly lower sole hieght (1/4"). I closed the transom and added a 26" bracket and a 225 Suzuki 460 lbs. I put scuppers in the side instead of the transom. Unfortunately that turns out to be right at the waterline and takes on water when I move weight to the stern.You mentioned using the original sole as a template. Does that mean you are leaving it in? That would be the equivalent of 4 sheets of plywood. That's a couple hundred pounds of excess weight. Also, are you pulling the old foam from the stringers and bilge? If it is soaked that's another 600 lbs. Before you decide to raise the sole make sure you get out all the excess weight. If not then 1" isn't going to be enough. IMHO.MD
