55lb or 70lb.
If it were me, I would purchase a 55 lb thrust motor and it would be a Motorguide. A 55 lb thrust motor will be a 12 volt system. Beyond 55 lb you'd need to move to a 24 volt system that would require two 12 volt batteries for the trolling motor. A 24 volt motor would offer around 80 to 90 lbs of thrust. Unless you're going to use your boat in heavy currents or strong winds, I'd opt for a 55 lb motor.
There is no direct correlation of thrust to horsepower. Horsepower is a measurement of "work" being performed. Thrust is simply a static measurement of force. In other words, "Thrust" and "Horsepower" measure two totally different things.
There are several places where you can buy a Motorguide Trolling Motor. You can visit the Motorguide website, or you can purchase a Trolling Motor direct from specialist boat companies in your location.
Jet power is measured in 'pounds of thrust' . The F-22 has 2 engines of 35,000 pounds thrust each. That's a lot for a small aircraft.
yes
It really depends on the state that you are in. There are different rules and regulations. In Kentucky, where I live, you have to license "anything" with a trolling motor no matter what (inflatable boat, canoe, etc.) It seems kind of silly though!
