"Not Good Vibrations" from my baby

[njlarry]

Hello all.
Finally got into the water. It seems to me that the boat has a vibration from 1500 to 2000 rpm. Not over or under that. Will check plug wires with timing light this weekend. Any other ideas?
1995 Volvo 302 HU with SX outdrive.
Thanks,
Larry

A close inspection of the prop, prop shaft, and u-joints may be in order as well.
