The swim platform is made of two layers of laminated fibreglass with a one inch thick balsa core sandwiched in between. I have access to the lower part of the swim platform from the bildge area under my cockpit floor. It is hard to believe your swim platform would be 10 inches thick. There must be a void under the top surface of your platform and the hull. In my instance, I plan on drilling over sized holes(1/4" larger) through the deck and removing 1/4 " more balsa core in-between the 2 fibreglass layers. I will then fill with Six10 epoxy and let it harden. I will drill out a 5/16" hole in the hardened epoxy to accommodate the 1/4" through bolts. I am sealing with 3M 4200 as well. I don't want to run the risk of water intrusion into the core, as it will wick and destroy the platform. The epoxy plug also will give a better compression factor between the backing plates and the hardware than the balsa core on its own. I assisted a friend in installing the system you have and the holes must be very precise or the upper plate will not slide on and off. Hope this helps you.
As stated by bud37, if you can't get access and see what's going on under your swim platform, Carver will know how that's put together, 1-920-822-3214 and ask for Brian. He's very helpful and can pull up your plans.
Greg, sorry to bounce between posts,
I just came across this description of what you did but I'm guessing the backing plates are angled and the nuts are not flush with the plates?
