Good Morning all,
I am currently troubleshooting a 2010 Evinrude Etec 90Hp for a co worker. I am told that the motor will start, idle, and 99% of the time run great. However, there has been a growing problem of the motor shutting down (Immediately with no progression downward, which makes me confident its electrical). After pulling off the cowl yesterday all appeared fine, except the air temp sensor appeared to be rubbed raw by the vibration of the cowl. The two wires (i believe black and red) both had exposed copper (Very close to each other). In addition, this copper appeared worn/burnt (leading me to believe it has potentially arced off each other or just dirty from the cowl). I have since done a temporary fix of isolating the two wires with electrical tape to see if this problem persist (the boat has not been put in the water yet with fix in place). Would you think these arcing off each other would result in the immediate shut down?
I have hooked up diagnostics and puled the following codes...
26: 12 volt circuit below range
58: Engine operating temp not reached
43: Engine temp above range
41: engine temp sensor circuit fault (This is on the most recent code and has occurred twice. Leading me to believe this could be the wires arcing. However the immediate shut down has occurred many times I have been told. I also as a test checked if the engine would start with the air temp sensor unplugged which could also be a reason for the code being pulled).
42: Engine temp below range
If you could please let me know your thoughts on this.
