kb here    bought a new minn kota  bow  foot control  trolling.  when i turn dial up to anywhere between  60-100   i cant control where ia'm going it wants to go right  then left   can not hold it in a straight line    what do you adjust to get it run straight  at high speed it goes right-left to easy   thanks   kb

Get out your owners manual. There should be a tension adjustment on the foot pedal to stiffen the resistance.  

My Minn Kota Edge 40 foot control has a steering cable tensioning screw on the base of the foot control underneath the area where the cables enter the pedal.  Hope this helps.

You haven't got use to the power yet. Mine does the same thing, it's a 84lb trust

I think. My buddie has a 36 volt 100 something and when I get up front I'm all over the lake.
