If you are going to trailer it, my old 14′ extra wide jon boat with a 15″ transom and a 20 horse planed out easily, planed out (eventually) with 3 guys with a 9.9, and moved pretty well with a little 4 horse too. There was no tippiness, plenty of room for 3 and safe to take the kids. Three guys could drop it off the bank (about 15 foot down) and lug it back out again. We dropped the boat/gear and a guy stayed and fished the first 1/2 mile while we took the trailer down river to the take-out point. Two guys could stand up while fishing/drifting without falling out. So why did I sell it????
We used a canoe to fish the really small streams. One guy would get out and fish the top half of a rock bank. The other guy would canoe halfway down, beach the canoe and fish the lower section. By leap-frogging that way we could efficiently fish several miles of quality water without getting in each others way.
