Technically that is not a true statement. Adding weights under the prop bolt will have an effect, just not a big one. It is not likely that adding weight under the prop bolts would be enough to get you where you need to be but adding weight will change the force vector and thus the distribution of mass about the crankshaft.

Just saying.
