Nice work. Your lucky the live well came out in one piece. Mine was in bedded in cabosil and I had to use an air chisel to get it cleared out. The area were the battery boxes sat was not really meant to be stringers. They play little if any in the structural integrity of the hull. Mine were rotton as well and I just tore them out. Having the batteries in the same location as the fuel tank was not a good idea in my mind.
