I would get a Minn Kota Maxxum. I had one on my last boat and my current boat has the MK Edge on it. The Maxxum is hands down a better motor IMO. It has the variable speed control and a much better mounting bracket and shaft. I will say that my Edge is slow enough on settings "1" and "2" to troll with though. IIRC setting "1" gets me about 0.4 to 0.5 mph and setting "2" get me about 0.7 to 0.9 mph by my GPS readings. I don't like Motorguide and don't use them so I can't speak on their current offerings.
