It's been a while since i owned the engine.

Of the top of my head, 14x10 was the suggested break-in prop in the manual.

All three props i listed are the same basic load factor.

I use (2 x dia) + Pitch as a basic formula.

So the 14x10 is (2 x 14) + 10 = 38

That model looks like it would be more suitable to a faster prop like the 14x10 or 15x8.
