I did the same thing last year. Decided to go with a glass boat for stability in rough water (winter fishing). Got a older ranger with a 150 on it, and the only drawback is the gas milage.
The only other boat I might consider is a stick steer with a 40 horse on it. It would not be as stable, but seems sitting in the front and not having to move after moving to a new spot would be good, and the gas milage of course.
