It's funny, the old timers tell the folks who are new to sailnet "Have you tried a search on this topic? It's been discussed a million times." Nobody tells them to also check the date....

Old thread, but good info. If my diesel starts acting up as stated I'll remember some of what I read here.

BTW I had a yanmar 2QM20 I thought they ALWAYS vibrated like that.

if it drops one cause of air that would be permanent though right, mine works just fine during normal use, its just switching from forward/reverse to neutral and just for I'd say a second...

What's wrong putting in a great suggestion to an old original post, I try to search archive before posting and this was exactly on my topic so why start a new thread....

Idle on the 2GM20 should be around 800 RPM. Lower and it vibrates, shakes and sounds like the pistons are ready to launch. I don't like to have it much higher believing it is hard on the transmission when shifting in, out of gear. There is an idle adjustment screw that you can use to adjust the idle to make it independent on cable stretch.
