Has anyone closed up the notch on a hull to stop over wetting the drive and make the water come off cleaner

The notch gives the drives cleaner water. Similar to putting them on boxes

Boat dragging its ass water coming off notch heading up at a 45 angle wetting the top of the drive causing a lot of drag

What hull? Maybe something else wrong with it. Notches are a good thing and that's why they were added. Lol

What power? What speed? Fountains have alway worked well with the notch. I'm not sure what you mean it's dragging other than you think it should be faster. If that's the case give al the info. Power? Drive? Ratio? Prop? Max rpm at wot?

Has the motor been dynoed? Where was peak power?

The 24 bravo 1 gives you 12% slip. That's pretty good.

Your slip is good. Sounds like your not making 600hp.
