Believe the vibration damper Capt mitch is talking about is the coupler between the flywheel and the outdrive. It is mounted on the flywheel under the flywheel housing. There are no springs in it. This is what it looks like
The torsional vibration damper is located at the front of the engine
and is mounted on the crankshaft. The crankshaft pulley is bolted to it with three bolts and a center screw.
Sorry to hear about the second ahole at the marina, as noted those engines are readily available from a variety of sources, in a variety of states of build, at a variety of prices (should it come to that).
Took a quick look at Jamesport on Google earth
, Long Island
may not be the place to find the most uh...economical... boat mechanics. I'd shy away from marinas
and try and find an independent with a good reputation, maybe talk to a Mercruiser rep for advice, or someone from a local boating
organization or club.
As a long shot, after listening again I wonder if it might be a problem with the exhaust
manifold. Loose bolt or warped flange or bad gasket
between the manifold and the head
does not flow into those manifolds from the heads, there could be an exhaust
leak that is hidden, intermittent and/or dependent on certain pressure conditions to make itself audible.
