1989 23WA Seacraft fuel tank replacemnt/maybe?

What you saw with the tank/foam and corrosion is what every 20 year or older seacraft looks like. Make sure the plywood platform is ok. Mine failed on one side, and the tank shifted down on that side and knocked the stringer off the floor. Potentially, very dangerous. These platforms were not "glassed" up, and rot from the bottom up, not the top down. Reach underneath and feel for any soft wood.

Thanks for heads up John, I was under the deck scraping foam off the tank deck and everything felt good, I will have to investigate further. I am going to get a local shop to install the new tank so they can glass in whatever needs to be done.
Most all the screw holes are worn out on the deck where the deck plate screws go, what is the beast way to repair them? Marine TEX or 5200?

I had the boat measured by the boat shop who will do the tank. We settled on 72X27X9" tank. If I did my math right, that will give me 75 3/4 gallons. That way the tank can be slid back into the tunnel w/o a hassle and then tied down. The fabrication shop here locally is about 2-3 weeks out so it will be toward the last week of May for the tank.
As far as the holes are concerned, they will do a little grinding of the bulk fiberglass that was used to hold the deck in solid and then glass a strip under the flange to have solid holes for the screws.

Picked up my boat yesterday and it really looks good. Easy fit and it has neoprene strips under it and foamed sides. I like the way they put flanges front and aft on the tank and the glassed in wood and stainless screws on each end to make sure it not going to move. I will take a couple of pictures when I get time. I just got home on Saturday night after a very long slow drive from East Lansing Michigan in rental truck w/dual axle car hauler w/a Ford explorer. I know we were way over weight, etc, but we did make it.
