Here are some more pictures after removing floor board. When I pulled the floor board, I found a lot of weeds and an old lock underneath the floor. Some of the foam was wet and I removed the wet areas an I am going to replace it with expanding foam. I also removed the foam along the seam where I found leaks and rivets leaking. I am going to seal the seam and reshoot the rivets that are loose. I am an aircraft mechanic so I have a rivet gun and bucking bars to do the job. The sealant is also aircraft quality so I am hoping it will do the job. I am replacing all of the floorboards and building a fishing deck with storage on the front from the seat forward. I am also extending the storage on both sides of the middle deck area and putting a seat post in the middle for a third fisherman. I will post more pictures when they come available. It has been cold here in ID, so I have to move the boat in and out of garage to work on it. I will get some more done this weekend.
