I think you may already have the best prop for your needs. I am running that same prop on my 05 X-star with the MCX engine. What engine do you have?
What's your rpm's at wide open? What's the altitude where you are? Your boat is lighter/smaller than mine so you should be hitting over 40 mph I would think.
Eric @ OJprops could help you. He'll most likely be along monday when he sees this thread.
