That is a major project. I went through it last year. It is almost impossible to get the tank out in one piece. I have a 1989 23 WA and it has 2 deck places. Both have to come out. If yours is like mine, the opening will be about one inch narrower than the width of the tank. I had to cut 1/2 inch off each side of the deck where the panel sits. Then after getting the tank completely empty of fuel and maybe flushing it with water to eliminate the fumes, you need to free up the tank from the foam and removing the screws holding it down if they are still in place. My tank was like 120 inches long and would not come out in one piece so had to use a saw zall to cut about 28-30 inches off. The I was able to use a come-along to lift it out. Hope this helps. I did replace with only a 75 gallon tank as the new 4 stroke engines are so much more economical than the old 2 stroke outboards. I am assuming you have an outboard?????????????
