Hi there,
I'm having trouble finding the right metal prop for my Continental A75 on my 1948 PA17. My A&P says it's the McCauley 1B90/7045. I called McCauley and they gave me 3 models; 1B90/CM7038, 7040 and 7045. McCauley said the 7045 was a cruise prop (I'd prefer the standard or the climb prop), but my A&P can't confirm that the 7038 or 7040 can legally be used on the A75. Can anyone confirm or provide paperwork that proves either the 7038 or 7040 can be used on an A75? Any help you can provide is much appreciated.
