This is very close to what I think I need:

I will be reading it a few more times to see how it can be useful. I am thinking that a R/C option (as at present) is good, but a completely mechanical backup would be handy.

Maybe my wording is a bit harsh.
What I am looking for is someone who has hacked into a Minn Kota controller to use a computer input (i.e. Arduino) to control speed rather than (or in addition to) the standard hand held throttle.

Fine. My point is that the "output" of the controller is related to the output of the rheostat, since that is at the business end of the controller throttle. That being said, do you know how the electronics work?

Ø a PWM controller, so the resistance in the rheostat is signalling the electronics with how much current to deliver to the motor?
Not likely: current is determined by load torque; no-load velocity is determined by the controller throttle setting.
