Arneson Surface Drive On 22 Classic . . . . .

[Carl C]

Has it been done? What are the thoughts and opinions on this.

[Pat McPherson]

Seen an 18X and heard of a Minx, but not sure it's worth the $$ and effort. Typically the change is made because B1 drives cant take huge HP. Even if you put 700HP in a 22C an XR would probably last 50-100hours...
The props for an Arneson cost as much as a Bravo rebuild...

I would think a Blackhawk would be a better option if you want a surface drive...

No, no Blackhawk. That is still an outdrive with weaknesses. An Arneson eliminates all of the drag of pulling a drive through the water and they are bulletproof. They don't have to change the direction of rotation twice through two sets of gears. Yes, they've been proven to work on an 18 but how well would one carry a 22? I've already blown a X1 upper because it wasn't up to the task of running 80s in offshore conditions. Blew a XR upper because the bearing preload nut backed off and wore out the gears in my Imco lower this year after over 200 hours on it. I also have something else up my sleeve . . . .

Chris Allard , CDMA , was working on a 22 with an arneson. Do a search and you might find it. Never heard if it was completed.

I remember reading that it didn't work on the 22. I forget where it was but I was surprised at the speed. Not good.
The talk was that it might work on a Blackhawk hull because of the extra rocker adding bow lift.

I think we should invite Jeff Hall to opine on his Minx experience.
I haven't spent a lot of time getting his impressions, but I seem to
remember he had porpoising issues and less than expected top speed.
Hopefully, he'll share.

I've read about other single screw boats that had less than wonderful
results. maybe we should look for really successful examples and figure
out what makes them right.

[Carl C]

The 22 definitely needs more bow lift and that is one of my main concerns; No way to trim up and get the hull out of the water.

Mine likes to porpoise. I've moved weight around and lengthened strakes. Three feet extra didn't make much difference.
212 lbs in the front made it better but not quite the right answer.
A 17.75x24p four blade Rolla made it much much better. Unfortunately it wasn't mine.
i need to find one for sale. Big diameter and at least four blade works best on my boat. I am currently running a 17x24 three blade cleaver.
Some longer tabs will probably help as well. I have the stock Bennets but I
may put some 280s on but only after I find another four blade.

Kenny's 22 wouldn't lift the bow no matter what.
I would think a 22 would need the inner strakes shortened to give it half a chance of working. A chopper prop Like a Hoss would be needed as well.
It's definitely a project.

Didn't Geoo make several modifications to his Arneson, and didn't Arneson even incorporate one of his mods into their units?

I think he is the one Carl should be talking to...Ed

Post Arneson's Pro's & Con's ???
BOY..... I hope everyone enjoys The Arneson Drive as much as I do.. The drive is real fast in it's normal state, if you have the bow lift. (ie. proper CG and or rocker). I needed to create bow lift with an added fin, which creates alot of drag. The fin gives bow lift, less hull drag, more drive drag. The fin pulls the transom down into the water and gives stability. The faster you go the more drag from the fin and the more power you need. Without proper bow lift you'll end up with bow steer, not a good thing, Trust Me... GEOO

Ed, Geo's was an 18X and that's a whole different animal! The 22 is bigger and heavier and needs some leverage to keep the hull from plowing through the water.

[Ed Donnelly]

Carl He had the same problem with the 18 if you read what he said.
He had to get the bow up on the 18. What he did by adding the extra fin got the bow up. No reason why it wouldn't do the same with a 22 ....Ed

[yeller]

You may be right Ed. I think it would work on a 22 also and I have no problem spending Carls money to prove it.

OK, I'm guilty of reading your post too fast. A fin was needed to generate bow lift on an 18 and the fin partially offset the benefit of not dragging a drive through the water. A 22 would need an even bigger and stronger "fin". It's not looking good for an arneson on a 22......

[gcarter]

Let's not forget that Donzi couldn't get the Blackhawk drive to work well on
a 22C hull. Just a reminder, rocker was added to the hull to get bow lift,
and all the negative handling problems that accompanied the hull change.

I still think we should look for a similarly sized single screw hull that's successful.
It may not be easily attainable..............
