Propeller question

My propeller turns fairly slow as it is driven by a 2.65 transmision with the engine turning 2,400 rpm. The result is at speed there is a definate chop, chop, chop vibration. The prop has been reworked and I have been told a 4 blde propeller while not as efficient will make it smother.
