The tank on my 1989 also had a leak, but was in the back and there was no foam in that area. Just powdered corrosion. It was a very slow seep until I had it out where I could see, put water in it and scrapped off the corrosion and the seep went from that to a pee hole. We did re foam the new tank,but put 1/2" poly strips under the tank to allow water to run out if any gets in. Then put mounting strips bottom front and rear instead of the side. My side mounting strips were loose, the screws had been worn out of the glassed stringers. The under deck platform was completely dry.
