Prop for 1980 family fisherman

[bubba]

Whats up fellas. I have a 1980 Aquasport family fisherman(cuddy cabin) It has the 470 mercruiser i/o. Someone stole the prop, and i have no idea what was on it. A friend gave me a prop he had sitting around, but now the motor is only turing 3300rpms, instead of 4200-4500. Does anyone know what prop should be on this boat? I never played with props, so it's all new to me. Thanks
