Trolling motors

Minn Kota offers a very large number of electric trolling motors.
Any thoughts about what model to get for freshwater sailing in a lake without major waves or currents?
Thanks!

Thanks for the quick response.
Any other thoughts out there?

I use a 2 1/2 horse Murcury....28lbs. Plenty of power.

Do you find the motor noisy?
That's the only reason I'm considering an electric motor.

Chuck, thanks.

Becuse gas engines are not allowed in two places I sail, I am thinking of getting a Minn Kota Enduro C2, probably a 55 lb. thrust since it is only a few pounds more than a 45 or 50.  I don't want to get stuck in a sudden squall or other emergency without realistic, maximum power.  I need suggestions on shaft length.  I'm looking at the 36".  Any suggestions would be greatly appreciated.  Also, has anyone had experience with a LiFe battery with an electric outboard.
