[C320-list] Diesel vibration, 1999 Yanmar

[Bill Hutt]

I'll try to raise the idle a tad and see if that helps. 
Thanks,

Bill

Hi Bill,

Ours does this if our Idle was set a bit too low.  If you pull the front
engine cover, on the Left side, is the governor cable (throttle) that's
connected to a little brass block.  There's a stop screw that controls how
low the idle can go.  Give it a few turns so that the idle is just a tad
higher.  With a little trial & error, we got it set so that we can throttle
down fast and it won't shudder, but still low enough for an idle and gentle
shifting.

Group,

While we're on the subject, when I quickly rev down the engine (as when
docking) I get a terrible shudder. If I rev down slowly, no issues.
When I first got the boat the mechanic said no big deal. Other than that
engine seems to run fine.
Any ideas/ suggestions?
Thanks,
