Last week my Ultrex was working great as usual and all of a sudden I could not move the foot pedal. It was like it was froze up but if I put TM on spotlock it would stay on spot, control head moved as it should and foot pedal also moved as it should but I could not steel with my foot. Called MK and they said I could not fix it and it would have to go to shop. I took pedal loose from deck and looked over could not see any problems. Re-installed and have fished twice since then with no issues it worked fine. Dont know why it did that. Today went to the lake again and fished about 4 hours with no problem then foot pedal locked up again. Control head spins freely and pedal moves when head moves. I'm afraid to put to much pressure on pedal and break something. Anybody have any idea whats going on??
