I bought a new 2009 2 cylinder 25 hp 4 stroke motor. I am on my 3rd hour of breaking in. The question I have is this: Why is this motor noisy and vibrates alot at idle? It is also noisy to me for a 4 stroke at mid throttle. Does anyone have a 2007-2009 motor like this with the same problem?
I thought "all" 4 strokes were quiet and smooth. Did I get a lemon?
