I agree with most everyone else. I have an OJ 14.25 X 14 also on my '07 21v. I run 2500lbs ballast plus family and I don't have any issues with the boat coming up on plane. With this prop I turn around 3100rpms at riding speed. Top speed is around 43mph with no ballast (although I never push it that hard).
Hope this helps.
