2000 90hp Johnson check engine light and warning horn question.

My boat is rigged with a 2" gauge with warning lights for "No Oil", "Low Oil", "Temp" and "Check Engine". I am looking for info on what will cause the "Check Engine" light and warning horn to go off. In a one hour trip the alarm will go off sometimes two times or not at all. I check the engine over and see no problems and in a couple of minute's the alarm clears. Not sure if this is related or not but the last trip out the tach started reading high,  what I trying to say is the tach is reading higher than the actual engine RPM, example at 4,000 engine RPM the tach is reading like 5,500

Thanks in advance for you time and any wisdom.

On a 90hp 2000 Johnson, there is no circuit for the CHECK ENGINE light. It is not used on that motor. My guess would be a faulty gauge or an intermittent short in the tan/orange wire somewhere in the system.

Bryansboat,

 

Johnson did not have a 90hp 4 stroke in 2000.
