Before you condemn the mount... is this an automatic transmission vehicle?
If so, the rear mount is hydraulic and the problem may be in the control
system.

Take a look at the mount. If there is a lever on the top of it and a vacuum
tube, it is a hydraulic mount. That lever should be in one position - firm -
most of the time and in the other - soft - at idle in gear. Often that lever
gets stiff and oil may or may not fix it. In addition, be sure vacuum is
applied when idling in gear. The hose or the valve that controls the mount
would be suspect if the vacuum is absent or weak.

Haynes says an expert is needed to troubleshoot the hydraulic mount system,
but the real Honda manual available from helminc.com has the simple
procedure.
