Hi David, Not sure we answered this fully: Under sail, weather helm produces some need to hold the wheel so the rudder is 4 to 7 degrees off center.
Under power, propwash creates a turning force that requires the wheel be turned slightly so the rudder is several degrees off center to correct course. Higher revs mean more propwash, more force to counter. I reiterate my belief based on using a meter, that I think the autohelm motor does not pull power unless the motor is driving. When things are balanced, she is at rest, drawing zero amps, and should never be warm to touch. Lastly, I suspect you may be experiencing voltage drop at the motor?

But what I really want to know from the group is whether the relatively strong pull to port while motoring is normal or whether neutral helm is normal.

I found that it was frequently cutting out while motoring (not sailing). The unit would simply freeze up and stop steering while the boat drifted slowly off course. No error on the P70 controller screen until I got an off course warning. I also noticed the wheel pilot getting warm/hot when this was happening which may be why it cut out. I also notice that while motoring, there is significant pull on the wheel that has to be fought to keep the boat going straight. Is that normal? I am guessing that the wheel pilot is overheating due to the power needed to continuously fight that pull?
