Hi all, Just wondered how much you can re-pitch a stainless prop? I got a stainless prop for a bargin price second hand but the pitch was a bit out of what I was looking for,but, I thought I would give it a shot, unfortunatly I am only pulling 4600rpm WOT so I fear I will not be able to repitch enough!!

You may be able to reduce by upto 2" however that is all. I dont know what the ideal RPM is for your engine but 2" may give you another 2-300 RPM. I doubt that would be enough.

If you need rpm, you could have the prop repitched as much as possible, but also reduce diameter. Rule of thumb is to gain 100 rpm for each 1/4" smaller in diameter. The alterations must be done in concert, or you'll lose the shape of the blade.
As to the original question, I, too have heard (from the prop shop I went to) that about 2" of pitch as the maximum you can reconfigure a prop.
