My recently rebuilt DPH-A outdrive's analog trim sensor is suddenly no longer displaying an accurate representation of the actual drive angle of the outdrive. It seems to be about 20 degrees off to the "plus" side. Meaning the analog indicator needle portrays a shallower drive angle than reality. Is there a way one can adjust the sensor, and if so, where is it located? Thank you so much- I'm a newbie to this forum.
