I had it done through a local shop. It was $450 or so.
The engine started and ran fine. But it you turned the prop over by hand, you could feel the resistance just before the impulse coupler snapped. The first time I did it, the prop stopped dead and my hand slipped right off it.
I have a wood prop and clean it after every flight. Sometimes it's not a bad idea just to turn it over and see how everything feels......
