The temp sensor that the arrow points to is for the ECM. There is another sensor somewhere for the gauge, but I don't know where it is located based on memory. As far as I know, the ECM and the gauge do NOT get a reading from the same sensor.

I can find the location of the other temp sensor for you this weekend when I have access to my repair manual. I wonder if the sensor for the gauge is off slightly, but the ECM is seeing the correct temps? Does the boat run well?

For what its worth, mine runs at approx 140 degrees all day every day...
