We have a 2018 L650 Fly. Over the years I ahve owned 7 Sea Rays. Three were built as “home runs” with lots of overall thought and design going into the boat. This is one of them! If you have any questions feel free to direct contact - thomaspetersen@...
If it was the CO alarm, then it was a low battery. SeaRay has the CO monitors wired so that if your battery drops enough it will alarm. Turning the generator on fixes it quickly. Not sure this is the same, but thought I would throw it out there.
