    While I would not normally suggest Automotive people for Marine topics...... this is one question best suited for a very well experienced Automotive engine builder and/or Machinist expert!

    In answer to your question...... if the engine in question requires a certain flywheel in order to externally balance the rotating assembly, and if that flywheel is not used, you will realize a vibration.
