I have a set of 24's 4 bladers too but have never put them on because I seem to run right about 5100-5200 with the 26's, so I think I am propped right.

I might throw them on this year though just to be easier on the drives when I have a boat full.

I'm about with Seaford. 454's with 250 Blowers not dynoed, guessing around 550-570HP a side. Low to mid 70's at about 5100rpm.

5050's boat runs great. Used to be scary until he put full hydraulic steering on it!

I have a set of 24 p 4 blades in great shape for sale. 850.00 includes shipping.

not sure if it will apply, but with my 500 efis stock and my straight hull tiger, i ran 72-73 if was real light..70-71 every day.
