Kinda what I thought too practical wise. Big bucks.
Where do we sign up as test dummies?There have been some put on smaller v bottom boats. They seem to lay down some stupid numbers. Like vastly exceeding any kind of sanity.
I'm having a tough time believing an 18' Donzi did 100 mph and the motor fit under the hatch.A member on the Donzi forum built one with Arneson drive for his 18 footer. He went way beyond 100 mph mark. Here's a pic of His boat.
Friend of mine had a Steve Jones built 28' deep V with single ASD 6 drive ca 1978, powered by a BB 460 ford, with twin turbos. Yeah, wasn't very good docking with the single setup, no problems with twins though.

Of all places, a Blackhawk was on CL here in central AZ. It was probably 2-3 months ago. No props, and asking 3k. I'd never seen one before. Same guy had a bunch of late 80s early 90s BBC aftermarket stuff, cranks, blocks, etc. I figured he ran out of money or interest and was selling off project parts.That's a lot of fucking coin for what is arguably one of the simplest propulsion systems ever designed/built.
That being said I have heard the same about low speed handling but would love to drive one some day just to see what like.
I would also love to get my hands on a blackhawk to see how my boat would like it, if at all....
My theory on them they were way ahead of their time a while ago but as sterndrives have gotten better technology wise that gap has closed. As stated this is just a theory.
If they really were a better mouse trap I would think you would see more of them around. As far as cost goes by the time you get done doing up #6 or 8’s I wouldn’t think ASD would be that much more expensive(maybe even cheaper). Also enough people buy fast boats with blank checks and I would assume some of the builders would use them if they were that much better. I looked into the bravo conversion a while ago and it was in the 15-20k ball park which is right in line if not cheaper then buying a new done up IMCO SCX or dual downshaft lower.
The 21 eliminator with one never ran well. The drive would pick the back of the boat up enough that it was extremely unstable. I believe it got wrecked and Teague is in the process of putting an IMCO SCX 4 on it. I saw on a Jet Boat forum one time a guy put one on a Glastron Carlson CVX 20, why anyone would do this is beyond me, I was always real curious to know how it ran.
On blackhawk’s, a guy in our local hot boat group has a 22 foot Superboat with a 650 horse 540 and a black hawk. It’s stupid fast and gets there in a hurry. He said he actually needs bigger props but they only made a limited amount of sizes and he’s maxed out. He claims it runs over 100 and while I don’t know if I believe that it’s not far off.
You must be talking about John? Sounds like it anyway.
Used to have some pics of a TX 20 with a surface drive on it, no idea how it ran, or where it was even from. Need to see if I still have them. Interesting for sure
I thought it was John's father in law's boat? John's Scarab and the SuperBoat engines are the same, Eddie Conrad built them. They both run like hell that's for sure.
Here's a 38' Formula with Arnesons that I've seen run. Crazy fast for a boat that size.

I think the thing about the Arnesons is the fear of the unknown. Theres a lot of boats out there that run really well with arnesons, Hustler 388s, Cigarette Top Guns over in europe. I think the owners of these boats have a little deeper pockets for trail and error vs someone with a single engine family boat. Theres not a lot of single engine boats I've seen work well with Arnesons, the 21 Eliminator comes to mind, there was someone trying a 29 Force cat with one that never worked right. Not to say it can't be done, but may take a lot of time and money to do so and I think that scares off a lot of people.
To top it off, theres a big thread on OSO right now about a guy who was trying to put arnesons on his Velocity and wasn't getting the parts or support from Arneson. Seems they may have some customer service issues as of late...
That boat picked up a lot of speed with those Arnesons. It wouldn't run over 100 before they put those drives on it.

Found them. Not sure if it was a TX 20, but looks like the rest I have seen.

Agreed for your every day family boat, although theres plenty of people who get cut up every year on bravo drives. For the big power boats, theres really no difference between the Arneson and a #6 drive, the props sit about the same spot.To your point as well I would think an Arneson would be about the most impractical thing possible for anything family related. The last thing I would want are my kids/friends doing anything in the water with that sharp prop sticking a feet out at surface level.
