Kevin, The McCauley prop needs to be between 69.5 and 71 inches on the C85 so that is OK. There is no pitch specified but there is a static RPM range that is. Your static RPM needs to be between 2025 and 2225. 44 pitch would be a crazy extreme climb prop. What kind of static RPM, climb rate and cruise are you getting with it?
