I sent my M76A M-2 50 pitch Sensenich to a prop shop to have repitched to 48 and got a call that the shop couldn't legally work on the prop.
It was explained that my prop needed to be replaced because of age. The prop looks great and the cub only has 1000 hours. The logs don't reflect when the prop was installed.
The cub is a 1952 PA-18-125 with a o290 D. I believe I could install a Sensenich 74DM6 48 pitch prop. My M76A weighs 24 lbs and the 74D would weigh 32.
What are the options....i don't believe the Borer prop is available for the O290. I want a climb prop and live at 2500' .
