25 hydros spinning in should put you at 4950 on the 502s. Might need 26 depending on where you boat( I.E. elevation, air density)

I have the exact same boat with 496 Mag HOs (which are almost the same HP). I'm running 26 pitch Bravo 1s (turning in) and get 5150 Rs. It seems to me that you should be doing better than the 4800 you indicate..
