Thanks 07. Got the gauge at my auto parts store and the little sender fit perfect. The Rhino is running at 180-190. In regard to the other poster I was looking at my service manual and did not see a thermostat in the cooling system. There is a logical place for one between the sender and bleeder housing. I guess the engineers at Yamaha decided that there was so little jacket area in the head that it would not do any thing but stay open all the time.
