Fwiw, Our prop shaft is on center but there is the usual prop walk caused by the downward angle of the shaft. I simply get the boat steering straight before setting the autohelm to hold course. That means the wheel will be slightly to one side, not much, maybe a third of a spoke. Once she is going how I want, at speed, right RPMs and direction, I lock the lever on the wheel autohelm drive and push the button on the autohelm control. Easy peazey.
