Feb 18, 2007 · Noise 34: The symptoms (see Noise 3: Rattling from Engine at Idle) are similar in that there is no noise above 1500 rpm and when the engine is warm. It's air-cooled, rear engine design is similar to that of a Volkswagen, or Porsche. OBC says "PPPP", reset time. It only comes back to normal if I turn the engine off and on again. Re: Root cause of Mercury 2-strokes' rough idle You were told right,these motors do not have a smooth idle. You may notice a general lack of power. Mostly from the right side. A rough idle/misfire usually starts out as being merely a nuisance, but if the causes are not identified and corrected, it may result in your engine not starting, or stopping altogether when you least expect it.
