I did not check the turn but I have the helm set for the most turns, at least 6 turns which is about the same as the auto pilot. The reason is to not over steer and then have to correct. Most of the time when the helm is on auto pilot and the auto pilot makes very small changes at a time so its not correcting. Per the rudder indicator very seldom is the rudder/helm turned to the stop, except in tight manuvering, but then the bowthruster is also used.
With the rudder hard over the stern is pushed to the side with very little forward motion. The rudder is 42” long and 30” wide, the prop is 38” and with the hydraulic steering does not take that much energy/force to steer. Anyway, I prefer more turn less responsive helm same as auto pilot.
