    My 2016 AR190 was having an Engine Comm Error and the tach would sweep back and forth the entire time.
    I dropped the boat off and had it looked at. Was told the speed sensor was bad and needed to be replaced. It was on back order, so I took my boat back so we could use it until it was shipped.
    We used the boat this summer. No issues other that the tach/speedometer not working, but we installed a Lowrance Hook 4 and used that for speed.
    Dropped the boat off this Tuesday and they replaced the speed sensor. No luck.
    Today they replaced the tach. Still didn't help.
    They said they took parts from a new boat to see if replacing them would fix the issue (to help diagnose the issue.)
    They are saying the boat may have been struck by lightning and that may have fried something in the computer. They are keeping the boat next week to try to diagnose further.

    Thoughts?

    Update.
    Dealer was able to find the problem.
    There was some corrosion where the engine wiring harness connected to the fuse box. The dealer ended up needing to replace the engine harness, fuse box and ECM.
    Odd issue, but I thought I would update in case anyone has a similar issue and can't figure it out.

    Struck by lightning. Lol. That translates to we have no idea what we are doing.

    I can't start my AR190, engine won't turn over, on board computer won't light up. If I keep the key in engine start position the computer lights up and I get Engine Com Error. You let go the key and everything goes out. I'm getting 12V from the battery, I'll try to charge the battery and clean the terminals to see if it helps.
