I recently bouht a used 25 M Yamaha prop for my 202 Champ. THe owner said he bought it used and never used it but thought it may have had some "work" done to it. Well it arrived today and I can say that the prop is a 9.9 out of a 10. I do think that it has been worked but wanted to run it past you.

-The blades are almost knife sharp.
- shines like new
- Three different punch stamps near back of the prop that read:
= GP31608
= GP31279B
= GP 30931

What are some signs that a props been "worked"?

My plan was to buy it run it and send it to you for a tune up. Would you still be able to work on it if someone else has?
