Yea, the Merc 4 strokes are not "proven", this is the early 2000's prototype. It is a 40hp, 4 cylinder, 4 stroke, 61 cubic inch, EFI, with a 60hp ecu. It has been run hard since 2002, 11 years, 6249rpm everywhere it goes. Does not burn a drop of oil, but, it is kinda slow with a fishing prop on it. Give me another 10 years with it and I'll tell you if it's a decent unit.
