We suggest our 24" pitch 4 blades. Turning them 5200 rpm should give you about 70 mph. I believe that is about where your speed will be. Please call and we can analyze your application.

Thanks,

Due to the vintage, I would use the Bravo propellers. The trailing edge configuration will give you the better boat attitude. Pitch will be determine by the actual HP and rpm you desire to turn the props.
We have these props for testing without needing to buy anything.
Let me know if you would like to try our test program. Otherwise we can determine the correct pitch with some other basic knowledge about your set up. Call me anytime.
