24 x 7 boat with 500hp
 

I have a 24 jaws with 500hp exactly. The prop i have is a 24p 4 blade.

Am i under prop'd?

What speeds should i see?

no
75 maybe

What gear ratio in the drive? What is your RPM's at WOT?

Id guess 70 mph with a 4 blade

What does the complete package weigh with people fuel and gear?

The 24 Superboat I used to own ran 76-78 w/425 HP. I ran a 28P Bravo up to 5000 RPM, 1.5R.

So your Superboat had 10-11% slip.
This is why I asked for the numbers.
RPM X Ratio X Pitch X .0009496 = theoretical speed.
Theoretical - Actual = Slip.

5000 x .666 (1 divided by 1.5) = 3330. 3330 x 28 = 93240. 93240 x .0009496 = 88.54

I think a 24" is going to be to small if its a 1.5 ratio drive. Most likely will need a 26 or 28.

Its a stock bravo. Have not tested the boat yet going to start with a 24p and see what it likes. I know the super boat is lighter than the jaws, ill be happy with 75mph i think if i blue print the hull it'll be close to 80
