Good day just wondering if anyone has experience using a ray marine tiller autopilot? I just purchased a new to me boat that came with one which the previous owner did not know how to set up. I went over the manual, and am having some issues with it. As the manual says, start on the course you want, press the auto button and install the pilot. It should then hold you on that course unless you press the plus or minus degree buttons. So what happens when I use it is I set my course, hit auto, put it on and for a while it seems to hold steady course but then after a couple minutes it will try to turn the boat drastically sometimes even a 180 and pressing the buttons doesn’t seem to change its course once it starts turning. It seems to me as though there is some calibration step maybe I am missing. If anyone has any input I would greatly appreciate.
