I have a 0200A Continental engine with total hrs (600hrs) and thinking
maybe I
should change out the rubber engine mount bushings only because they
have been
on the plane for 25+ years. They look fine but maybe a little sag on the
bottom
ones. Is this usually just an eye ball assessment or a "must do" item
based on
#years on the plane?

Thanks.Larry

The rubber must be getting a bit hard by now. New ones would smooth
things out some, and bring the engine up into proper position.
But that engine: 25 years and 600 hours is not good. I suspect it
could have corrosion problems that might bring more grief than old
mount rubbers.

Maybe the rubber shocks saw service with other engines? But no way the
rubber is doing its job after 25 years.
