I have a 36v MotorGuide, and it used to buck and turn sharply to the left when on high, to the point that I would have to get going in a direction at a slower speed, and then ramp up power. I had one of the cables break, and after I got it back, the buy who repaired it had tightened the cables, and now it doesnt buck.On the MotorGuide, there are two threaded sleeves near the foot pedal. By extending them away from the foot pedal, you can tight the cables. I would suspect there is something similar on the MinnKota as well. Give it try before putting the troll perfect.
