I have a 88 250 FV. Two years ago I re-upholstered the seating. I believe yours is much like mine. The "L" shaped seating, cushion is one piece and the backrest is four pieces. They are all secured to the wood base/backrest with large velcro type strips stapled to the wood. I had to use the old seat framing as patterns, and completely rebuilt them with new marine plywood. It took some time, but I did it over the winter while the boat was laid up. The base frame was ok, so I left it alone. The dry rot was pretty much confined to the backrest framing, and all of the wood supporting the seating pieces.
