I have a 16' Smokercraft Tracer that I can load 4 guys in and push 5 mph with a Yamaha T4, I would think you would be fine unless you are really loaded down. The only thing I don't like is it is a bit loud when trolling mach 2 for silvers against the wind but the weight and fuel economy are hard to beat.
The other thing to consider is where the prop is, if it is below the hull it will push much harder than if the lower is too short for the boat.
