Overheating Mercruiser – Problem finally solved Running cold one minute @ 75 degrees then running hot at 195 degrees Weird symptoms , watch all three short videos to learn from Dennis Allen of Affordable Marine Service in San Diego California.
Boat type , Searay with Bravo outdrive and Mercruiser 350 MPI
VERY rare type problem that I have never seen in over 40 years experience daily working on Mercruiser engines.
Watch all 3 very short video clips no more than 1-3 minutes each on how we find the problem after checking all the usual things such as raw water pump , removing outdrive looking for the famous Bravitos trasnom blockage problems etc.
This boat came to us after being at several other shops and no one could solve the problem . They already installed all NEW exhaust manifolds , Raw water pump impeller , thermostats etc.
We installed clear hoses so you can see into the cooling system of the 350 MPI Mercruiser to help with the diagnosis .
Watch and learn , you may want to try clear hoses next time your looking to solve a cooling problem on any marine engine .
this will be a very popular 3 set series on Mercruiser overheating problems
