Ferm brings up a good point, most boats will create a resonance when trimmed all the way in, I don't know if its cavitation or just vibration going thru the drive, but once you trim it a little, it quiets down, certainly would be cheaper than any other solution. How bad is this thing vibrating? Is causing you mixer to go flat? Rattleling the wax out of your ears? or just a slight annoyance that you notice only because you worked on it
