I just installed a closed cool
I just installed a closed cooling system on my brand new 5.0 MPI Mercruiser. After the initial fill and test I noticed the starboard exhaust elbow running hot. I took the boat for a test run and at high rpm the elbow runs cool. The engine does not overheat. I think that there is not enough water flow at idle to cool both exhaust elbows. Could I have a pump problem even though this is a brand new engine? The dealer told me when I picked up the boat that they changed the water pump housing because it was cracked.
