Default What pitch dual prop should I purchase?

Hello,

I am repowering a 25ft Chris Craft Launch that has a 496 HO (425HP) with a Bravo 3 drive & lower unit. I am ready to purchase dual stainless propellers but I am not sure what pitch they should be to ensure I have the proper RPM and max performance. Any input would be appreciated!

Thanks,

Mark

How fast do you think the boat should run? What ratio Bravo 3??
BBlades has a test program and I would definitely use that to be sure.

Like Griff said , you gotta know your gear ratio before anyone can advise with certainty , but I'll tell you this based on what I run , if you've got the 2.0:1 ratio you'll want a 26" propset .
If you've got the 1.81 (or whatever the next one down is) it'll more than likely be the 24" set.
