Most people run a 25" Renegade 4 blade on those, Not the fastest but a great all around prop.
24" Raker "original" is a fast prop and has good hole shot. These are the 2 most common props found on the older big stratos boats. A lot of people really like the Mercury Tempest plus prop. It will be the fastest of these props and possibly of any prop. It has good hole shot and is tunable with their plug system. You will have to buy a hub conversion kit to run it. I would try any of these 3 props if I was you. I run the renegade on mine 201pro xl with a 200hp motor. It worked the best for me because I carry a really heavy load on the boat most of the time. The others were faster but suffered on holeshot because of the weight.
