I'm learning more about 'coupes in general, and the '48 E model I just purchased, through this forum! Although the previous owner couldn't tell me what kind of prop the plane has, I figured out pretty quickly on the flight home that 7148 must mean climb prop. Now Ed confirms my suspicion. Departing a 1000MSL strip at 50degF, I was pleasantly astounded to see 800+ fpm on the VSI. When I only saw 100mph at 2350rpm, I felt fairly sure that I must have a climb prop. I was alarmed, however, at seeing only 2250rpm on the takeoff roll, although acceleration felt good and rpm was normal in cruise. Now I know why. Are there published climb prop performance numbers to substitute for the standard ones in the POH, or am I going to be a test pilot this summer?
