I talked to a prop shop. They say they can repitch a 19 pitch prop and make it a 21 pitch prop. he said that they bend the last 1 1/2 to make the prop a 21. I would think this would interrupt the flow and add a lot of drag. Has anyone done this? How did it work?

Thanks for your experience,

As it was explained to me by Mr. Cavanaugh from Mercury, the outer edge of the blade is what works at high speed and the inner portion near the hub is only working at hole shot. So for top end you work the pitch on the outside of the blades. If that is the case then you should be fine repitching the ends. All props have variable pitch so a little more shouldn't add any unusual drag.
