I think the 140 should be perfect (hopefully). I never new that propping it right could make such a difference. I think my yami is propped wrong.

These are two of the props that the guy is offering:

-13 5/8x15 (michigan wheel ballistic)
-13.25x18 (Suzuki stock)

From reading these boards I see that a 15X15 seems to be popular so I'll probably just buy a new one once I get the engine.

But I have to take one so which seems a better fit for the V?
