Boat previously worked great, now wandering terribly?

I’m not great at analyzing logs. Can anyone take a look here and see if we can figure out whats going on? This boat was previously running perfect. I changed the sonar out but did not modify the autopilot hardware or software. I did do a compass recalibration after the sonar change. But now the boat is wandering terribly and isn’t even close to being able to hit waypoints.
