The model (1A90-CF) is very common. Your pitch (42) on the other hand, is very fine. This would be an extreme climb prop. (46 is considered "normal" climb for a land plane.) Is your plane on floats? Have you checked that it meets the static RPM requirements?

yes it is floatplane but on wheels now. I'm looking for more speed if anyone has a cruise prop for sale. I don't want to re-pitch this one, its great for short strips.
