mshugg thank you for your advice on the fiber glass tiles did you cut a hole in the core and then glass it in as a core or is it just glassed to the bottom of the deck? looks like you cut a hole in the pic
Here is my $.02 (and what I did).The first time I did a rebuild of my 170 I did the lip and laid 1/2" fence pickets on the top of the stringers to compensate so the new floor would be supported. That lasted 10 or so years and then I lost my mind after having some rot from under the deck caused failure in the front of the console, and I removed everything from the inside of the hull. I made detailed measurements from 1x2s attached across the hull before and after the gut and new stringers. I lifted the liner out of the boat - I cut the liner so it kept the side walls.With a clean slate I was able to raise the floor height 2+" when I made new stringers. I reinforced the entire hull with 1708 and epoxy, installed the new stringers I had made and then glued the new floor down and attaching it to the hull sides. Then I rolled the cap back into the boat and marked where i needed to cut the liner to mate with the new floor height. I then cut the walls of the liner to mate to the floor making sure to leave the necessary gap behind any rod wells in the liner, etc.
and then I lost my mind
