Default SOLD: Catto 68x74 three blade prop with nickel leading edge

I'm converting to a constant speed propeller on my RV-7A in mid-August and will no longer need my Catto Model: 3M68X74NLE, three blade fixed pitch propeller. It is a 68 X 74 : (68" diameter, 74" pitch) composite propeller with a nickel leading edge. It should have ~100 hours on it (still flying it today). Included are:

- The propeller
- Matching spinner spinner
- Mounting Bolts
- Saber 2.5" prop extension
- Saber 7"x 5/8" crush plate

Price is $3,000 + shipping - Sold

Currently on an YIO-360-M1B, 180HP engine, static RPM is 2220 @ 1,280' airport elevation.

Here's some detailed flight test data that I collected over time, your mileage may vary:
