RE: Overloading an engine

ORIGINAL: Juice

What happens when you over prop an engine in such a way that the max RPM is 20% lower than with a typical prop?

Does it damage the engine? If so, does the damage occur immediately, or does it happen over time with repeated flights with the larger prop?

Thanks,

Horsepower is lower when running an engine outside of the power band and the engine will usually run hotter. Little damage is done unless the engine seizes but it generally is not a good idea.
