does a I/O have a thermostat

[roffey]

The reason I thought thermostat was the temp went up real high.. then went to the middle of the gauge, almost like the thermostat opened. This is a bigger boat, 26 ft. When testing I had it WOT for the most part. I may have been pushing it a little. It was my impression if you have the gas you can run wide open all day.

I will check the water pump.... and by the way.. even with 4ft chop heavy winds and bow spray soaking us.. if was f**king fantastic.. I love it.
