2000 MariStar - Vibration

Throwing this out there for some opinions. My friend called me stating the his boat, a 2000 MariStar 210VRS w/ LTR Engine, is having vibration issues. It doesnít accelerate well or hold speed well. Vibration is prevalent in gear but also in neutral, hence the mystery. It has also been noted that there is extra rattling noise in the drive line. It should be noted that there was no underwater gear strike. Engine is running smoothly. So what could be the cause...right now my smoking gun is the drive dampener. Any thoughts? Iím hoping to troubleshoot it myself in the next couple weeks. Just wanted to get some other opinions as well. Thanks everyone!

Can you post a video? Could be a bad coil or failing crank sensors causing misfire.. could be old wires.

I'm with Mike. When's the last time the boat had a full tune up? You'll also get the same types of issues if you swap wires to the wrong plugs (don't ask how I know this please, it still hurts after all these years).

A damper will definitively cause a rattle but shouldn't cause the performance issues.

Could also be the harmonic damper coming apart on the front of the engine (the lowest drive pulley for the belts).

Thatís what me friend is suspecting. He is a Mercedes mechanic so he knows engines very well. Has about 20 hours since tune up, and ECM was replaced 2 years ago. Unfortunately the boat is 2 hours away from me so I havenít had an opportunity to troubleshoot it myself, and I canít get him to tow it back to town.
