Kiwi prop RPM/speed

[pjcomeau]

I'm looking for information from people with a Kiwi prop with an M-25XP.

when I ordered it, I asked it to be set to 19 degrees (10") pitch as suggested by others on this forum.

As mentioned in other postings, I had to replace the transmission and I have reason to believe that the refurbished transmission is not working properly (It was very stiff upon arrival).

Does anyone have RPM/speeds, max RPM in forward and reverse? I max out around 2600-2700 rpm in forward and around 1100 in reverse (reverse seemed adequate until I tried it in heavy winds).

If my tach is reading right, what speeds should I expect @ around 2200 RPM? If I'm not getting the speed expected at 2200 rpm, could that mean I'm under pitched? I'm assuming overpitched would be faster @2200 but the max RPM would be lower or could over pitch still mean slower speeds at 2200 rpm? I never did confirm that the prop was sent to me properly pitched (other then on paper).

Thanks,

Pierre
