Hello,
I have pair of 2GM20FC's with SD20's on my catamaran. I don't see
the connection between stalling and engine mounts. If the engine has
an imbalance, such as one cylinder not firing, or a misbehaving
folding prop, there will be a lot of wobble that can be very dramatic
on the soft saildrive mounts. The wobble sounds more like an effect,
not a cause.


I have a Yanmar 3gm30fc w / SD20 Saildrives that stalls when reducing RPM. I
think I've isolated the problem to be with the engine mounts. The engine
wabbles quite a bit when de-throttling and stalls. Starts right up with no
problem, idles and engages in forward and reverse with no problem. It stalls
when coming down from 2k rpm. The mounts are from 1998 so they are probably
needing to be replaced. So my question is how do I install the new mounts?
I'm told that I can 'jack' up the engine from the hatch using a 2 ton lift
and supporting rope, block the engine, remove the engine mount side bolts and
slide out the old and slide in the new. Seems straightforward though curious
if anyone has similiar experiences.

Thanks,
Bob
