This is the actual RPS and the Starboard base plate it's mounted to. It's critical to the performance of the Autopilot that the sensor be installed so it's mounted in-line with the center line of the hull and then bolted down in this position. I found it easiest to line up the base and top plates before installing the set screws so I had nice 90 degree angles to work off of. Once the RPS is installed you must then make sure the rudder does not over steer the device.
If the rudder can turn more than the RPS can handle it will break plain and simple. I had to adjust my rudder stops ever so slightly just to accommodate the RPS. Installing the threaded connector rod is simple but it will need to be cut to length and it took me two cuts to get it perfect. Never cut short and always err on the large side when test fitting this piece.
Once all the hardware is installed you simply run the RPS data wire to the Autopilot control head and connect it.
