Was out this weekend and I noticed that I couldn't steer my older Minnkota Power Drive trolling motor with the foot pedal. It would still throttle up though, but I had to turn the motor by hand if I want to go in a certain direction. Do you think it could be the foot pedal or the power board in the motor? Here's a place that tests the pedals.
