the thermostat opens and closes the keep the engine at the correct temperture, the tale tell is only an indicator that the water pump is pumping water. the temp of the tale tell does change as the stat open and close.

you can get and infrared themo and check the temp of the block. these come in real handy. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93983

Welcome to iboats.

I would check the t stat to be sure that it is in fact opening as it should. If it is stuck shut, the cooling water circulating in the powerhead will heat above the specified value (145F) that the t stat is suppose to open at, thus sending super heated water out of the tell tale. The tstat is suppose to constantly monitor the temp and open and close as necessary to maintain that proper temp.

If in fact there is an issue there, I would test the alarms to be sure that they are functioning as they should.
