I just finished my FC470 project (pics to follow).
The floor was the most challenging part but it is working well. I was lucky enough to have the bow section including the wooden board and eyelets still in good shape.
So I took a piece of Marine Ply 19mm thick and the biggest I could find (1200x2400mm). I had to trim the width down to 1000mm and the length was a bit short. To bridge the gap between the ply and the existing board I cut a pice of ply to go underneath and a piece of steel to go on the top. I carpeted the under piece of wood and drill matching holes though everything and secured the whole lot like a sandwich with 6 bolts (3 on each side). The nuts I used underneath are bolt plates that screw in allowing you to undo and redo the bolts when you need to remove the floor. I carpeted the whole floor using good quality marine carpet and put two support brackets in the floor at the back attached to the transom for support of the engine.
50HP Tohatsu went in yesterday and first run tomorrow.
I'll post some photos of my first run.
