What about the prop? I was tightening an APC 19x8 on a Saito 220 the other day, and wanted to make it really tight (maybe I have an insecurity issue). All of a sudden, the prop made a noise, as if it had cracked or something. It really freaked me out, and I had to inspect it very closely before I dared to use it. There was no visible damage, so I suppose it was OK, but I'm just wondering if in fact you can damage the prop by tightening it too much.
