I believe it’s a early 70s hallett v drive. Would it be competitive? Above all else I just want to go fast in a straight line. Is it super heavy and would it take a ton of power to be actually fast? The power limit on an engine I can build is about 800 horsepower what kind of speed could I reach with a mill like that with the right gearing? I’m new to all this
I have attached some photos, any help appreciated

Without considerable hull modifications you would be right around the triple digit mark. If you used a drag hull (a runner bottom) of good design then with that power number there is no reason 110-115 should not be within reach. Also, a runner bottom would handle the power much better where the Hallett would be much more touchy.

So I should wait until I find something like a hondo sprint? A runner bottom is just a flat bottom right?

Flat vs runner

if you look at the cavitation plates on a flat and then on a runner you will see a noticeable difference. Runner bottoms have tunnels that range from .5” deep to 2” deep. These tunnels make them much more efficient and therefore can be faster with the same amount of power. They are also very often considerably lighter than the old boats of the sixties. Do some searches for runner bottom v-drives and you will see that they are the pick for straight line stuff. Now if you really want to go fast on a straight line then I would consider a hydro. Easier to drive and even more efficient with the use of the power

so in your title you mention "racing", are we talking about an actual sanctioned race or just "racing with your buds on the weekend" kinda racing?

The answer to that would play into what I would want as well.

My initial feels about that hull are, most 70's hulls used older technology materials, which were heavier and they tended to be laid up a lot thicker as well. Often the propshaft angle on these older boats were not always the best for performance due to a larger angle at the strut. It all comes down to what you want it for. A fun weekend beater, it would fit the bill. It'll be a money pit though, but all good boats are!

Run as fast as you can from the Hallet. You'll never be happy when a blown Cole runner bottom pulls up to you and leaves you standing still. For better resale try and find a Cole. Canyon and Mako's are fast and well built boat's. My friend had a Hallet hull similar to this one your looking at but it was a jet and it was a big heavy pig.

I had intentions of posting something similar, but looks like I forgot.

I think you'd likely be way ahead to find a mid 80's to 90's era flat since they're much better built and setup with more modern setups.
