More info needed
There's more to selecting a prop than you appear to understand. You need to know the engine HP & rated RPM, the transmission ratio, shaft size, distance between the shaft & the hull ( to determine the prop diameter & allow for necessary clearance ) , length and beam of the boat at the waterline, displacement. If you can provide that information, find the Michigan Wheel on-line site and they can give you a professional assessment of the prop for yor boat.
