Not too big of a deal to enlarge the hole. You can go to a marine supply place like Overton's and get a porthole/access-cover that is larger. It'll have the larger flange included that you need to replace the one you remove. Your biggest problem will be figuring out how to cut a 7" hole evenly from the smaller one.......FWIW...they do make 7" hole saws... ;-)
