I've got a 2000 Osprey 175 with a 2000 Johnson 90, and one of the console gauges has several indicators lights in it, such as High Temp, Low Oil, and Check Engine. I know what High Temp and Low Oil are for of course, but what would cause the Check Engine indicator to illuminate? Mine isn't illuminated, but I've never had one of these indicators on any of my other boats and I was just curious.
Thanks
