It probably did not smell of gasoline because none leaked into the cavity. #76 sustained stern damage (a 50 power boat backed into it at the dock, but that is another story). When I removed the foam three years ago, it smelled of leaded gasoline (not sold in Calif for about the previous ten years). I replaced the foam with the new stuff and painted. If poison gas from fire is a worry, cover the foam again with plywood. If you do get a good fire going, the fiberglass is likely to burn like crazy anyway.
