I have a 2008 SE2600 io with a mercruiser mag 350 bravo engine. Once engine is up to running temp, I overheat when I Have to slow down below 1200 Rpms. After talking with numerous shops and mechanics, I was steered to look up Bravoitis online. It looks like a manufacturer defect in the design of the cooling system of bravo engines. There is an aftermarket part available for around $30 and now mercruiser has a redesigned part $ 20 to fix it. My local dealer wants to pull the engine($5000-$6000) to put in a $20 part. Why Hasn't there been a recall on this and can the repair be done without pulling the engine? The online forums are killing mercruiser over their lack of support for their product and this issue.
