I'm looking to buy a 70's Starcraft 18ft fiberglass boat, it is set up like a row boat with bench seats, and a tiller, it doesn't come with a motor so I'd like to know what is the smallest motor and the biggest motor I can run, don't need to go fast as it will only be used few hundred yards off shore mostly but also used for walleye, but I will have 3 guys in it weighing a total of around 700lbs plus light gear. Any help is appreciated, also would it be hard to set up for steering wheel and controls? Thanks guys
