First everyone is probably going to tell you to get a lockhart repitched 3 blade. They are really good, probably the best, but Dave doesn't make a whole lot of them.

Right now I'm running a Bolly 16.5x12 with reshaped tips and I really like it. The mejlik 16x11 is really good on that engine too. There's a company called cleveland props or something that makes a mejlik-like 16x11 that may be even better. the OS 160 will turn any of the above very well, and it will get that idle speed down pretty slow. Down lines will be a lot smoother.

But this is like asking which engine to use.....heh.

Good luck and see you in 3 weeks!!
