I have had my MinnKota Ultrex with BT, and Link on two separate boats in past year. The trolling motor spotlocks well. My issue is when selecting “N” on the remote. Neither boat would/will follow the course in Advanced or Legacy. I have completed calibration and offset multiple times. I think I got a “bad” board. The trolling motor never seems to “correct” and stick to projected course that is plotted on the Solix.
Question 1: if I took it to authorized service center not sure they be able to diagnose the problem. On appearance the trolling motor works. Would they be able too?
Question 2: What board could be the culprit? If I just wanted to purchase and install?
Question 3: I usually see every thing worse case scenario, could it be something else?
