I replace my 95 gal. tank in my 1998 ,21 SeaCraft with a 60 gal 4 years ago , no problems, I had a lot of extra room around the new tank so we did use some foam to fill in some space,no problems,they do expand a bit the first few times you fill it, and they do not recommend foaming in these tanks..
