Yamaha 252SE Repeated Communication Failure Errors

2021 model year. After ~30min on the water, I start getting a smattering of different errors: GPS, Stereo Remote, Joystick, BCU, Port Engine, Starboard Engine, etc. like “BCU Communication Failure”. Sometimes they beep for a while with the error and sometimes they beep for a half second and stop.

My transducer needs to be replaced, and I get a “Transducer Communication Failure” when I start the boat but only that once.

The boat runs perfectly, other than the annoying error beeps. Has anyone successfully solved this on their own? I can’t get it into the dealer for a few weeks and it’s boating time. I tried replacing both batteries and that did not help.
