Every prop company has a calculator on their site to determine what prop is correct for what boat. However, you will need to know the HP of your engine, the shaft size and taper, the prop rotation and reduction gear, if any, on your transmission. You can't just ask others with the same boat as they or your POs could have changed engines, shafts and transmissions.
What prop do you have on there now? Why change? It is best to talk to the prop company. In addition to the information @capta said you'll need you will need to know the distance between the center of the prop shaft and the hull. There needs to be sufficient clearance between blade tips and the hull for the prop to work efficiently.
