I have a 1946 415C with 85hp Continental engine and metal prop. About one year ago I had the prop back plate replaced. The old plate had a jagged break almost all the way around about 1-2" from the outside. We now notice that the new back plate is broken almost all the way around very similar to the break on the old plate. Just prior to replacing the last plate I had the prop re-pitched and balanced.
Other than replacing the back plate again, does anyone have a suggestion on what I should do or what is causing the plates to break? Thanks, Dennis Hatfield N2738H
