Status: offline 		Bax, I use a 15x8 prop with the 1.08. Would a 14x9 three blade work as well? Need a bit of clearance. Pulling about 10lbs.

Status: offline 		A 14 x 9 3-blade propeller would actually be much more load on the engine than the 15 x 8 prop you were using. You may need to go smaller, like a 14 x 7 or 8 3-blade, or even a 13 x 8 3-blade. You want the engine turning the same RPM as before, and then you need to adjust for how the airplane performs.
