    What engine temp should my FX Sho Cruiser be at, check engine light has been coming

    My buzzer and check engine light is coming on, Its been really hot here and my engine temp was 103 the other day in the water. I do have the cooling upgrade kit on it too.

    Its a 2012

    No one knows what the operating temp for a 2012 Yamaha should be?

    140-170......a overheat will trip a temp light not a check engine light. When it does it again you need to pull the code, not sure about FX model but on FZ you hold down mode button till a code comes up

    103 Is too low that will cause rich condition and gas in oil

    next time the light comes on shut the ski right away and push down the display buttons and hold them for 5 to 10 seconds while the buzzer is beeping and it will display a code. Once you get the code look at the manuel and see what that code is.

    here is a manual for your ski its from my drop box, if you have issues with it, let me know.

    also 103 is not hot at all, thats the same temperature a human being gets with a mild fever. Imagine all the explosions that are going off per second in your 4 cyl engine and then think about that number again. You most likely have a different issue, over heating the ski would cause it to go to limp mode, are you experiencing this? also like other have said, a temp light will come on, not a check engine.

    I do have the cooling upgrade kit on my ski but the highest I have seen the temp is 114, can that be right? I will check the codes, thanks for all the info.
