Fastest single engine V bottom boats

[Greg G]

The fastest larger V bottom is from Tuff. 24'9" of pad V fury from the great Northland. Hull only said to weigh 800 lbs, it has clocked 119 mph with DBR 15" 300XS.

Without question the fastest 25' pad V anywhere in the world.

Only 10 mph slower than the Allison...

Agree Noah, the Tuff is pretty incredible for 25'. Also worth noting that they do all the work in house from start to finish.

I believe Blake in Canada has the fastest tuff 24' 300XS 118 with more to go still testing

[DangerNewb]

That's pretty incredible. Does anybody have an idea of the HP of the DBR motor? I get it's light and narrow, but 118 with a single is strong. Not many 20 foot boats, including tunnels, will do 118 with a single 300. Very impressive.

I think they are about 325-330hp with the DBR.

A stock pre 2000 model 300 x is about 285 after year models are 330, i would say anywhere from 350 to 450+ dependent on the build

[hellbents-10]

I think prop hp on the 300xs is about 305-310 stock and about 330 with the DBR kit, its just a air inlet, tune and flywheel.

I got you, I was thinking x

His is a stage 1 flash only.

Also, not that they count because they are sterndrives but the 24 and 28 both have crushed Allison’s speed in lake boats. The 34 is next level

[hellbents-10]

I think with time you could get a 450r working on a 24 and go 130. I don’t have the wallet to try it yet though lol. I need to work mine up to 110 with the current power then I will move on.

Well I cannot wait to throw a wrench in all this!! In an effort to be competitive in a specific class of racing, I have shelved my 21' Eliminator outboard build for a certain October Race and begin a new chapter with the Velocity 22' hull. It will be powered by an LSX with twin Nelson racing turbos, Holley Dominator control and yes, a Blackhawk Drive using the XZ 1.36 or 1.25 gear sets. I am rigging the hull as I would an Aircraft with all weight balanced for level flight... including my fat ass in a Left side seat.

I have no doubt that an Allison is the fastest outboard boat produced ever with the proper rigging and a driver who suffers with a "sickness coupled with an obsession" for speed... but when the river dumps into the windy lake or say 45-50 other boats are churning up the river, a small OB "potato chip" hull is not going to go 110mph for 2 hours, let alone four at that speed!

For my plan to work, I have to be able to keep this puppy running 5100 rpm for the duration of the event... which for an LS is easily doable. After the success or fail of this run in October or possibly in preparation for such, I will run the LOTO Shootout as well. Just have to see. Right now, all I have is a bare hull and after much searching, the Velocity 22 is the best one I have found for the task at hand. I am certain there are some who will say the Blackhawk is not rated for 600+hp and I will agree, with the once exception... the gears it was produced with THEN are now much stronger when using the diesel versions made for the BravoIII. I can also tune the "Hit" from the turbos to be more progressive and since this is not an "Offshore" application where the hull will be exiting the water with wave action... it might handle the consistent load to push a hull much lighter than earlier versions of Chris Craft & Donzi Boats that the drives were originally designed for.

This Cigarette 24' could reach 112mph with a stroked Viper V10 engine making 605+hp with a Blackhawk drive and 31" props.

I agree... I could build a boat with a Nelson Racing Engines 1400hp twin turbo LSX and a drive for less money than buying ONE Mercury 450R!! As soon as most people realize this, the shiny new outboards are going to become a bit dimmer in the light! The 1100hp pump gas engines start at $28K and fully optioned are about $33K... of course, if you wanted to budget build a 450hp to 650hp with a single eBay turbo, you can do that for less than $5K!

LSx power!!!

The Allisons will run better than you think in rough water, you just have to take your time. I have had my light XB 2002 in Lake Maurepas when it was rolling. It was no speed demon, and my Howard would have been much faster. That is like apples and oranges though if you give the Allison flat water. I made it across from the Tickfaw to the Manchac Pass and back in the rough and stayed dry!

Had a Mod VP, but the Allison is the most fun to drive for me.

Far as the SS 2000, everyone has told me about 110 was where they got stupid. The down force from the large wind screen, which is nice at times, creates too much at speed. Pushes the bow down which is not what you want on a V. That may have been a problem with the "lip". My XB was modified by a fellow in Dallas, TX. I did the same my SS on a boat ramp with feeler gauges, a long straight edge, and a sanding block, made it .020 all the way across. It took a couple hours as I sneaked up on the sweet spot, it is a pussy cat now. You can drop the throttle at 95 and it will just coast down instead of hooking. Speed goes... well I have a 280SS on it now, so we shall see.

I ever buy new OS, it will be a Tuff boat. No doubt one of the best looking and best running V-hull platforms out there!
