Hi Pete & Ian
The motor is Lycoming 150hp 0-320 narrow deck,straight mount,
standard carb, came off an old cub
prop is Hoffman HO-Y 72L\170 constantspeed ,this gives an
economical cruise of 170KTAS at 2300 revs 23 inches at 5000 ft

Hey Russ
Can you post a photo or a link to a picture of the prop . I couldn't find it when I did a google search.
Ian

Hi Ian
