Sorry to hijack your thread, but I have a similar situation in my BF200. The aluminum floor panel makes a slight aluminum foil sound when stepped on, and has a little give that I'm not too happy about. I took the panel out, and it seems that the bottom aluminum piece has separated from the honeycomb area. Was it ever determined where to buy a new sheet? I looked into replacing it with wood, but the section on my boat is 1" thick. That would make a ton of additional weight vs. the aluminum. Any thoughts?
