I have just purchased 1999 Chaparral with twin 350 MPI and Bravo ! stern drives. It sat for some time as it only had 20 hours on it over the last two years. So I decided to have it completely serviced after i lost an impeller on the starboad side. SO both impelers and thermostats were replaced along with an oil change. After this was completed the engines would idle great and run about 160 degrees, within minutes underload the temp would runstraight to about 220 degrees so I promptly returned to the dock. I checked to make sure the thermostats were not installed backwards, could the impellers be in backwards, the old one that was not destroyed has a curve to it and the houseing indicates a LH ROT. What could be causing both engines to be running hot after this work?

Thanks

Any chance you hooked the water hoses backwards?
