Recently purchased 2007 Yamaha 200 HPDI. It has about 50 hours on it. Cranked it Saturday, warning buzzer sounded. Not a solid beep, but beep-beep-beep. Both oil tanks full, nothing blocking the water intake, peeing fine. I put it in gear to get away from the launch a bit, and it stopped. Idling in neutral, buzzer was sounding, as soon as it was put into gear, no buzzer. Thoughts? Suggestions?
