"I just replaced my thermostat
"I just replaced my thermostate because it was flucuating and running on the cold side (140). Put a new thermostate in that is rated to read 160. At idle it's reading 160, until I reach cruising speed it reads 180. how can I check if there is a blockage of water from the lower unit to the thermostate. I have a 2003 5.0 mercruiser mpi bravo 3."
