Did you hit anything? I had a slight vibration that was caused by a slight bend in my propeller. After I had the propeller reconditioned the vibration went away.

Agreed, if this just started, you may have hit something. You may have wrapped a bunch of weeds or a rope around the prop. It could also be that an old strut bearing finally wore enough to cause a vibration. Loose motor mounts and fasteners, rotten stringers, and engine run-ability issues can also lead to a sudden vibration.
