I'm in a similar situation to the OP. I have a Benmar Compu-Course 220 hooked up to a Benmar S-Power unit. The power unit seems to work but the boat will turn slowly to starboard when I engage the Compu-Course 220. I'm considering replacing it with a pypilot.
I'm not sure what kind of motor controller is required since the S Power unit seems to have a different input. Ships power is 12V, 20A and then the control is from the Compu-Course controller in a 0V to 8V range with a +4V reference; three wires: 0V (SIG GND), 4V REF, +8V. This appears to be fairly low current but I don't know how much.
Any idea if a controller for this exists? If not, I suppose I could build one from Pypilot motor controller plus voltage divider.
