It would be interesting to know if it was the controller or power supply that caused the deviations... I"m guessing the power supply
Yes it did work before even with bad compass, but I feel that the course correction has improved. I sailed again today and I really felt the improvement when sailing close hauled, I used to get caught into the wind but this time I felt like the AP was able to hold the course better.
I am planning on changing the enclosure boxes with something smaller, I will try to reproduce the issue with the dc and motor controller to see what caused the issue

The MPU board containing the IMU should be horizontal not vertical, and the yellow capacitor should face towards the front of the boat. I think the magnetic heading is only correct with this orientation.
(Would love to know if I'm wrong. My autopilot would be better mechanically if I could mount it vertically like you've done!)
As said by Sean, it does not matter once you level the sensor. Also for the compass reading you can actually correct +/- the Heading so it matches your regular compass. I think it's in calibrate\heading
