What are the pros and cons of both the Power Drive and regular cable foot controlled trolling motors? I'll be replacing a bow mount 1989 Minn Kota cable foot controlled trolling motor on a 17' Bass Tracker. I have a transducer mounted to the bottom of my current one and would like to do the same to the new one or get the one with the universal transducer inside the motor, but it's a little pricey. Anybody used the universal transducer?<br /><br />Thanks for your thoughts and opinions.
