I have minn kota maxum 74# thrust that jumped to high randomly also, I found that the little white flat wire that runs from the speed control switch to the control board had a short and the only way to fix it is to replace control board which cost 185.00, I just bought one for mine, hope this helps you

Minn Kota Maxxum jumps to full power by: Gary
I have a brand new Maxxum Pro 80# with the same problem. No matter what the throttle setting is, it will randomly jump to full power on its own.
If you figure out what the problem is, I'd sure like to know what to do about it.
