[C320-list] Westerbeke 30B noise and engine mounts

[Larry Frank]

I have Hull #246 with the Westerbeke.  I can move the engine slightly when
I grab a sturdy part and lift or pull.  I can also report that the engine
seems to run smooth with little vibration in neutral at all RPM.  In gear
that can be quite different for many factors.
