I'm looking for a club prop I can use to break in/test an engine. I
could use a regular prop I suppose, but the engine will be on a test
stand and I'd rather have something with a reduced diameter for
safety.
The engine will be producing around 180 to 190 hp and I'd like to be
able to run it up to full power/rpm for extended periods. Maximum
prop rpm will be 2400. The prop hub has a standard bolt pattern.

Any ideas? Suggestions?

Hook it to a generator and sell the electricity to the local power company?

Not a half bad idea, until you do the math. At 180 HP at the prop you're
talking 134 kilowatts of power. That's probably _only_ 120 kilowatts if the
generator is 90% efficient. (Actually, I hope it is better than that, because
the leftover watts go into heating the generator!) It seems to me that a
generator capable of handling that size power conversion would be expensive to
rent...
