I have a OMC 140HP -85 outboard that has done faithful service. When I
jerk
the flywheel back and forth I notice a small radialplay with a "clonk"
sound.

Is this normal or are the main bearings defect?? It runs OK with no
knocking sounds.

I don't know much about it...but that doesn't sound good. If you start
the engine -- does the flywheel move in a circle or is it somewhat
elliptical. Maybe putting a white mark on it would help you tell??

Or maybe the centrifugal forces keep it centered when it is rotating.
