It is not the prop. I ran the original prop that came with the boat when I bought it three years ago and, though less noticeable, the harmonic vibration was still there. By reason of deduction-I have come to the conclusion that it is the jack plate, even though it seems tight and strong. It did not do this when I first bought the boat. I wonder what happened?
