Gary,
I have a 1989 Sceptre, and when I pulled the tank out last year, this is what I found. It wasn't leaking, and 95% of it was fine, but there was deep pitting where the foam that held water was touching the gas tank. I don't know if it would of gone one or 10 years, but the pitting was more than 1/2 way through. As for the junk, you might want to remover your anti siphon valve, you really don't need it on an outboard as long as the lines are all above the top of the tank. Those will give you fits if you have junk in the tank. I put a 148 gallon tank in mine, but I run a lot of long distances.
