Check the shaft zincs. Since they can hollow out, unless they are new, replace them.

Every year I have been getting a little more vibration and I am trying to track down the source. I had the usual things check such as cutlass bearing, prop balance, and engine mounts. I have heard that I should also check the prop shaft alignment. When I am sailing and have it in neutral the prop spins freely. Could it be out of alignment and prop shaft still spin easily?
