Now that I have my temperature gauge installed, I need to know normal operating temp. range. At what temp. do the thermostats open?

Blizzard,
According to my Yamaha shop manual for my 2000 C115, the thermostats start to open at 118-126 degrees. They are fully open at 140 degrees.
Don't be too concerned if your temp gauge is off a little - my Teleflex that I installed shows thermostats regulate at 130 degrees - you are just looking for what is "normal" on the gauge.
If you want to get precise, you can calibrate the gauge and sensor in a pan of heated water and accurate thermometer, but it's really not necessary.
How did your water pressure installation come out?
