I have 2007 26 Outlaw 496 HO 425 hp and when I purchased this boat the prop was missing. They put on 23p 3 blade, turned to rev limiter and only 57 mph. Up graded to 25 pitch 3 blade Power Tech 61 mph @5100 rpm. told this should go faster?

You are in the ballpark with that boat...they run 62-66 MPH with 496 HO. I would test a few other props to see which one you like best but your very close on speed.

What brand was the 23p prop? These boats come from the factory with 23p mirage + props (at least I know 25OL do, I'm assuming 26OL do too) I would try that prop first!

Testing a 25 Mirage + to obtain a base line for Lab Finishing is the best go fast option.
We can help with that if you desire.

Thanks for replying and thinking of trying 24 pitch bravo one.

Try every prop you have the oportunity to try. If you like the B1, it can be modified to decrease the stern lift it will have.
