Which prop for new X star with the 8.1L?

My 06 X star with the 8.1 L came form the factory with a 14.5 x 22 prop. The boat has tremendous pull but idles a little quick. Top end, fully loaded with 4 passengers and ffull uel (no Ballast) is about 46 mph at 4700 RPM. I think I am slightly over propped. What are others turning for a prop with the same big block?

13.7X19.5 but the boat has an additional 3000lbs added to it.

The dealer installed the 13.7x19.5 on my boat with the 8.1L and I felt it was too slow for my use so I had it switched back to the 14.5x22. We almost exclusively wakeboard, wakeskate and surf behind the boat and the 14.5x22 works well.

With the 13.7x19.5 our cruise speed was too slow. All of he lakes we tend to use are larger and sometime we would cruise up to 20 miles to get to where we would ride.
