My trolling motor is an older model and it also does this. Finally got tired of readjusting it and gave up on it. I have now learned to look at the foot pedal instead to see where I'm going. Example, tilted back to me and it's pointed left. Tilted away from me and it's going right. In the flat position and it's going straight ahead. After just a little while of steering this you should be able to manuaver with the same ease as when you were looking at that lazy arrow. A lot of the time I just steer by feel and never look down.

Just my thoughts! Good fishing to you!
