There is a bit more to the story. The change 25-degree variance coincided with an increase in throttle RPM by about 200 RPMs. Now, my engine is an older Perkins 4.236 that is 100% mechanical. But as I mentioned in a post yesterday, I had the rudder modified for a fishtail/Schilling that supposedly improves close-quarter maneuvering. Possible the adaptaions are asymmetric. Will check in 10-days when I haul for fresh bottom paint and some punch-list items. I may have the modification reversed as it doesn't really seem to assist much. Was not expensive to do, and hopefully not much to undo.
I have also noted a persistent 2-degree port-rudder on the rudder angle indicator, though that is opposite the cocked-angle of the boat. Definitely could be calibration.
Bottom line is I'll spend some time tomorrow in protected waters of San Diego and calibrate the system. I'll also likely order the SiTex Sat Compass listed a couple posts up.
