I have a motorguide 40# thrust foot control. My problem is if you turn it on high or med you can't control it with one foot it will flip one way you move it a little and it will jump the other. Is there any way of adjusting the cable or tighting the motor where it will be stiffer to turn. you look like a drunk trying to walk a straight line when going to the next dock. any help would be great Cub48
