If you go to a propeller with larger diameter or larger pitch, you will get lower RPM from the engine, and lower performance. If the engine's running well now, then just keep running it as it is. We normally prop the engine so that it will turn over 11,000 RPM. An APC 13 x 8 propeller is usually used, but you will get more noise.
