Try putting in 23.2 for the slip calculator, since thats what a 24 bravo measures out to be about. Slips even lower.

I'm with you, I think he's down on power. Whats the build specs?

Yes. That's the direction I was headed is his power is off. Not an issue with the notch.

With that cam, not surprised its going faster with the smaller prop. Try a 22p bravo one.

Where did the HP peak ?

Crude Intentions 01-02-2017 07:17 PM

Also is the hull stepped or not?

Crude Intentions 01-02-2017 07:19 PM

Then let's go to the dyno. What exhaust on the dyno and what exhaust in the boat. You can easily leave 40 or more from dyno headers to marine manifolds.

dspad 01-02-2017 07:22 PM

Stepped hull
Harden cast aluminum manifolds
Dry risers wet at the tip

dspad 01-02-2017 07:23 PM

Dyno headers. When on dyno
