The bottom is critical to wring the last bit of speed out. Mine was blueprinted for the '96 Powerboat test. Identical boats with HP500's were at least 4 mph slower than me, especially the newer boats around the 2000 time frame as the mold was in need of some serious reworking.
Focus on a triangular area from the transom/chime intersection to a point 4' forward of the rear of the pad. That area needs to be perfectly flat, no hook and no rocker, for this hull to fly.

You may need to "blue print", "true up", "straighten", what ever you want to call it, before you run 100+...
I had a bud take the hooks out of a 24' Formula an gain 4-5mph...

Some bottoms have a "rocker". Just the opposite of a hook. Put a long straight edge on the bottom and you may find high spot causing the straight edge to rock.
Either can be by design or a flaw.
As I understand the posts above, Velocity boats are supposed to be flat/straight for best performance.
Block on the 7-8th should be a great run...

Finally getting this project wrapped up. It took a lot longer than I thought it was going to, but I should be in the water in a week or so. I'll get some pics of the boat you will have to let me know what you guys think.

26' Velocity
A few years ago,I had a 26' Velocity 1994 that was running a 850 SC. I had the hatch raised 3 inches and added extra side vents. I would suggest that you have dual rams for the extra stability these boats at high speeds need all the drive stability you can get as there is only a little of the boat in the water at 100 MPH. The Velocity with big power requires a lot of work to keep it running straight. I was running a Hydromotive prop that made it difficult to drive from 80-90 MPH. I changed to a custom built Spinalli and to 1.36:1 gear ratio with a beefed up Bravo with a Imco std length lower, which helped greatly with the handling. My boat ran 103 on GPS in fresh water on Lake Cumberland in Ky. The Velocity is a very good riding boat that is deep enough to handle rough water, good luck on your repower project.
