Been noticing vibration coming up in some threads again lately. Then an idea hit me. I have an O'Day 35 with a Universal M25xp and vetus 75 engine mounts. Vibration below 1000 rpm pretty rough. 1050 to 1100 idles very well. Above fine. Could having to increase idle for smoothness indicate that the spline is wearing in the damper plate. Just a thought.
