ZF Marine transmission sounds like cement mixer

Update...drive/damper plate in good condition. Pulled filter...no debris. I do think the engine may be just running a little rough. I will tune up tomorrow. I will also take a dip and check the running gear under the boat.
 
Tune up and injector cleaner. We went for a run and ran WOT for 5 minutes. Like new. Thanks for all the input. It is great so many people have time to help out. Thanks again.
 
Its hard to believe the noise that tranny will make from a engine in need of a tune up. I could not believe it. I thought it was a lot worst then it turned out to be.
