Opps: I believe it is the other way around: you need something flywheel-like up front to make up for lack of weight and inertia of a wood prop. Something like a Landoll dampener would not be necessary with a METAL (flywheel) prop as the weight and inertia is already there.

Actually Archie is correct, the device is a harmonic dampener, or to put it different it absorbs alot of unwanted vibrations which in effect smooths out the power pulses. A balancer is usually a static action to correct a shaking motion, the harmonic balancer is an active device doing its thing as the engine runs.

I work with these on a regular basis, and can assure you the a wooden prop will
absorb and dissipate orders of harmonics where a metal prop will not.
That is not to say it cannot be used, however.
The dampener may add some flywheel effect but why would anyone install it for that
purpose? We are not incorporating it for flywheel effect. The purpose of any dampener
is to absorb torque spikes which are generated in every internal combustion piston engine.
