Thanks Griff, thats what I was looking for. Now I can run it and see where my top rpm is at and start adding prop to bring it down. I am guessing I will end up with 26p Bravo 1.

What Griff said on the RPM's.
Switching from a 3 blade to a 4 blade prop is a different animal. Too many people throw props on without understanding the characteristics of blades and geometry. Getting a "better cruise" speed out of a 4 blade might totally change the characteristics of the boat. My Panther loves 3 blade Mirages, runs good with 4 blade Spinellis, really doesn't handle good in rough water with Bravo 1's and is a death trap with hydromotives. Get use to the handling and characteristics of the boat before making prop changes. See how it carries the bow, how much stern lift there is, does it chine walk or porpoise. Try to borrow props before purchasing. Each prop has it's advantages, I know, at one time I was prop poor with 8 sets on the wall... JMO
And my 37 AT likes Bravo 1's

Those things need more cam, it`s done by 5200. Spin it to 6K !

Those are some great engines! I have new 427cid stroker small blocks. Dyno max HP at 652.3 at 6200 rpm. Max torque is 610.2 at 5000. Haven't had in the water yet so we'll see who that translates. It is making 580.9 hp at that same 5000.

I've had a small block 327 cid in a Chevy II all my life and these things like to spin!

Looking forward to watching this one!

It should be pretty balanced with the small blocks and aluminum heads. I have a set of new 25 Mirage+ and will start there. It has 23s on it now. My old Magnum sport ran very good with 280 small blocks spinning 23s through TRS. When I compare this to my current boat it just seems like a no brainer requiring a bigger wheel with more horsepower, no transmissions and Bravos.

I think you'll be surprised how hard the 25 m+ is to spin

Great balance of Torque and Horsepower. As everyone knows, you need some good Torque as well as Horsepower to spin props for speed. Torque sometimes gets over looked. You feel Torque on the water.
