Doug,
This is my earlier comment about Yanmars and the engine beds and it doesn't need a lot of explanation.
Excessive engine vibration isn't the problem as much as the fact that the Yanmar is a light weight motor that lacks enough mass to dampen much of its own vibration and motion and the engine bed it is on in the 360 and 340 isn't adequate enough to do much either.
Re: 340DA Twin Yanmars
I've seen 2 of 340DA's with Yanmars. Our dealer won't order them anymore because there isn't enough boat under them to provide a good platform. The Yanmars pretty much shake a 340 to pieces. You can hear everything on them rattling as they sit at the dock idling.
I happen to own 2 Yanmar diesels in other applications and they and Kubota are about my favorite engines, so I have nothing against the engines, I love them. These motors in this boat just isn't a good match.

Hello Frank,
If you see the above photo's, don't you agree that there is a big difference between the (size) of the structure of the 340 and the 360?
On the photo from the 340 you don't see the stringers, because they are under the engines.
Also don't forget the 360/380 is 4000 LBS heavier than the 340.
Do you also know that there where problems with the Yammers on the 360/380 models?
