View Full Version : Bennett Propeller Identification

07-09-2017, 07:27 PM
I have an 84" propeller with eight bolts and two "Bennett Propeller" stickers affixed to it. It appear to have "ob - 110" stamped into it. I would like any information on what type of propeller it is. (aircraft vs. airboat etc.) I would also be interested in any other information such as date of manufacture, type of plane it might have been used on etc. I intend to sell it, so any valuation information would be helpful. The previous owner spray painted the metal backside of the hub. (poorly) I have attached photo of the propeller and all identifying information that I could find.

Have the tips been cut down? A photo of the tips end-on might help.

I have attached some photos of the tips. Not sure if they were cut down or not, but they are more squared off than what I see on most airplane propellers.

Yes, the outer portion of both blades is missing. That's usually from a ground strike and makes the prop non-airworthy. I'm just guessing that the outer 6" is missing and that the prop was originally around 8 feet in diameter and may go as far back as an OX5 engine. (Check the hub dimensions here (http://www.woodenpropeller.com/Hubmeasure.html), although a match doesn't necessarily prove that it wasn't something else.) What's left of it resembles a "toothpick" style like this (http://woodenpropeller.com/JN4toothpick.html).

The damage and alteration to the tips really reduces its value significantly. If in fact it's an OX5 prop the metal hub may be worth more than the prop.

I will check the hub measurements and see what I come up with.
