Winterizing the Yamaha this weeken, I ran it in a clean garbage can full of water. After running the engine for approx 5 to 6 minutes the warning buzzer went off. I quickly shut the motor down and tried to determine what caused the alarm. The oil was full and the engine didn't appear to be HOT. I had a infrared temp gun available to me and the engine head temp at approx 165. The #1 and #2 sparkplug temped 165 and #3 temped 155.<br /><br />Any thoughts?
