Guys i am putting in new power in my cafe. I am going from 465hp to 630hp and i have bravo drives with four blade mercruiser 26p props. I realize that i am taking a big chance with the drives. ( New drives are my next purchase. ) I think that i can change the pitch of the props. The motors also dynoed 670lbs of torque. What do the experts recomend on a new prop size.. Thanks for all the help..

Whatever you go with, make sure they only have 3 blades. The last thing you need is solid hookup.

What did the engine builder say your max rpm should be. How many rpm could your 465hp turn the 26 pitch?

JeffC

I could turn the 26s at 4900 to 5200

JeffC

the builder is putting rev limiters at 5400

SKRAMER

I would try the 26s and get a base line. Then call b blades or throttle up and get their opinion. But I think maybe a 28 bravo one. Might be the ticket.

If those are 4 Blade bravos and won't work after your engine build, drop me a PM if you want to sell them

I have Innovation 600+ in my 94 and run Bravo 4 blade 28 pitch - blueprinted. Have 1.5 Bravo's.

That should keep you in the 60 MPH group no problem.

Actually the 80 mph group on GPS
