impeller pitch questions
I have a question about a Solas Concord 13/19 impeller and its pitch.
I used the prop pitch gauges that are available on this site and made a homemade pitch gauge. My 13/19 impeller reads 19 on the trailing edges but the leading edges are right at 12. Should I adjust the leading edges to be closer to the 13 pitch or is this normal for the stock Solas impellers. I know that the pitch is all over the place when they leave the factory, but this impeller is pretty consistent.
Just looking for your thoughts.

After working a few thousand 13/19 Concords by now. The TRUE PITCH in degrees AVERAGE between 11-11.5 / 18-19

Island Racing, Thank you for the information.
With that being known, would there be any improvement in acceleration to increase the leading edge to a true 12.5 or 13 on this prop? I realize some rpm loss will occur. And I know if you change the trailing edge to a 20 you will gain some top speed, again with some rpm loss.

I to am thinking of a repitch I also have a new 13/19 solas imp. Is the gauge to test your current pitch hard to make?
Bye the way I am the one with the 1200R for sale that will not sell. I think I am going to keep and maybe do a complete tear down this winter, and rebuild bigger. See yah...
