The trolling motor on my 700 (Tracker model 50 48lb/12v) took a fair amount of abuse at the hands of the previous owner, including a bent shaft that was straightened. Overall, it works well, with one exception: A couple of years ago, the tension control knob snapped off as I was trying to tighten it. No matter how much I tightened it, the shaft still rotated very easily in response to the pedal. No tension was being added. Hence, I applied too much torque and snap she went.
