No idea if this fits on a 150 or 152. I just saw this and thought I would share just in case $800 obo.

The only McCauley props approved for the C150 per the TCDS over it's production history are the GCM, OCM, HCM, DCM, MCM and PCM in no particular order and varies per year/model no.
Be very careful buying a propeller outside of aviation sources, especially when no times are mentioned, or any documentation included indicating it is airworthy.
An un-airworthy rejected propeller painted with shiny Krylon black enamel and new McCauley stickers make a great wall hangar for your bar or "man cave".
