How can I determine the pitch for my prop? I took the spinner off and measured the prop. It is 69.5 inches.
I cannot see any markings, so they must be on the back side of the prop. My logbook says it is a McCauley 1A90, but there are no further comments. I have a C-85 12F. Cruise is 105mph @ 2400rpm thnx, Rick 611GC
