Propeller for SA100 / 0-290

[Dana]

I'd like to replace the prop on my plane. Nothing wrong with it, the plane performs just fine, but it's an O-290G and there's a note in the aircraft papers saying "aerobatics not recommended" due to the thin flange (it does have the reinforcing plates). [FONT=&quot]I’d like to replace it with a wood or composite prop to put less load on the thin flange of the -G engine. A lighter prop will also help with the aircraft’s nose heavy condition.

I'm actually not sure what I have right now.[FONT=&quot] I can find no markings on the propeller, though I haven’t removed the prop so I don’t know if it’s marked on the front or back face. The initial entry in the aircraft logbook says M-76AM (incomplete part number?), s/n 50-184. Elsewhere in the aircraft papers there is a 1984 receipt from Pacific Propeller for repairs to a 74DM6-0-58 s/n A43409, though there's no mention in the logs of the prop being replaced. There is a log entry stating the prop was reinstalled after being reconditioned in 2007, but no mention of model or serial or who reconditioned it.

[/FONT] [FONT=&quot]I measured the prop at 72” diameter and 61” pitch, blade angle measured on the back face with a Warp Drive protractor 27” (75%) from the centerline. That angle at that distance could also mean it's a cut down 76x58 prop.

Cost wise (I'm always broke) it could be a wash if I sell the metal prop.
