Congradulations!! No power drive does not turn as fast as a cable steer but what is nice about them is you don't have to keep your foot on it all the time like the cable. Co pilot allows you to control the motor from anywhere in the boat using a small module like a TV remote. You can carry it, put it around your neck or even attach it to a pole. Auto pilot is great. It keeps the boat going in the direction you point it. You could get by with a 40lb thrust but if I were you I would get at least a 55. It never hurts to have more power than you need but can come in handy in high winds to get you out of trouble.
