Have you experienced any vibration from the engine/transmission on the Sea Ray Sundancer 380D CAT 3116's? I'm still getting use to having diesels (love them) and at times I get this "feeling" that there is more vibration at idle/low speed coming from my port side... my wife thinks I'm nuts when I point it out, as an example, we were moving along at about 7 knots coming through a no wake zone area of the lake and I felt there was more vibration than normal based on a "rattling" I was hearing from my boarding doorway and when I looked at a bottle of water on my dash I could see the "vibration". I put the port engine in neutral and shut it off to see if it went away and although it wasn't as much with just the starboard engine running, it was still "just barely there"... when I did the same test by shutting down the starboard engine and just running the port engine, there is just a little more "vibration"...
I read there may be something about the port engine turning the prop counter rotation vs the starboard? Something to do with why the port engine consumes a little more fuel than the starboard? ... but from the thread I was wondering if this could be the vibration I sense at times?
Do you think there is a "normal" amount of vibration with these diesels/transmission? OR should they be really smooth with zero vibration?
