Stock 05/06 Impeller Pitch
What is the pitch? I just checked on a stock one I have (using Hydrotoys pitch tool) and the pitch on all the blades is all over the place...not one blade was the same to the other two. Also checked the Yamaha site and there's no info on it, unless I missed it.
Also, what is the difference between the stock impeller and the 14/20 Dynalfy in terms of the blade design?
I'm thinking about having it true pitched and try it out before getting the Dynafly. Is it worth it or just wasting my time.

This is all that I could find in the '05 supplement, but I don't know how the OEM number relates to the average aftermarket number.

Thanks Crazy. I read that too, but couldn't figure that out.
I just rechecked the it looks like the leading edge is somewhere between 13.5 to 15, and the trailing edge is somewhere between 18 to 19.5.

Yes Rafi..15 degrees all they way through. Thanks for the pic John, looks like that Dynafly is a little set back, huh?

i thought it was a 13/18 3 blade stainless with 15degrees all the way throughout. Let me know if that is incorrect because there is not much info on this...
