You are absolutly correct in your comparison to a 6. I was more comparing to a bravo style drive.
If the boat was designed from the ground up for surface drives, design time would be about the same.
For retrofitting, or modifying a hull for surface drives/diesels though...........

Even with a Bravo as a the "Yard Stick"

We are only 4" longer. Not a deal breaker and certainly will not present a storage problem.

We do not require more engine room space nor intrude into the cockpit.

The same engine will sit in the same location with a Bravo as it will with the Arneson.

The bottom will not need to be modified or specially designed either.

Oh, and the Arneson will not break when you go over 300 hp in a diesel application.

Ahhh that monsterous BRAAAAP!!! When you get on it. Be the best sounding boat when the gun goes at the billfish tourney and out front too :D
About the surface drive vs out drive thing. It has nothing to do with the gas vs diesel argument. Gas or diesel the surface drive is gonna perform better. Look at what OSG Racing did with Flexi Drives on a Donzi a couple years back. I think Donzi still has some videos on their site. Watch the videos you will see how the suface drives and out drives run different.:p
Joe I ran for the company whos drivers have no log books. The logs are kept in a main frame computer in Omaha Nebraska. Logging is done via the Qualcom. Ya know the big blue trucks that aren't liked very much by most other drivers. :party-smiley-004:
RIK you forgot the Arnesons don't disintegrate like the Merc #6 drives do when you lean on em with some good old fashioned Diesel torque.:p

Here is a Donzi with Arnesons like you are referring to.

That video is kinda bubu the one running has Arneson drives. The one standing still idling has Merc #6s. Also if you look real close the decals are slightly different. :p

BTW end of this week my boss is flying in from Tokyo. After we get done with San Diego. We might be putting in an appearance over at Dan's. Did he get the roof fixed?:D

Any news about bobby's? :(

The Big Blue Company Line =>:signs069::signs069::signs069:

Also Big Blues Trailers are still mostly blue. But the used truck market was over saturated with blue trucks. Now Big Blue's tractors come in more colors than floats at a gay day parade.

Bravo to asd7 - yes you are corect,
Bravo to ASD 8 w/ 16in drop down, not so much
http://www.twindisc.com/Downloads/CA...%201010989.pdf
plus you need a 12degree to 6 degree wedge.

Just wondering why some people here seem to think that the only way to make a diesel run in the 70 and up range is to have multispeed transmissions? Also, what is with the misconception that arneson drives don't handle as well, or manuver around the docks as well as a sterndrive?

Oh ****.

You are comparing a Bravo to an ASD8. Get real.

The ASD8 has a larger torque capacity than a SSM#6 and your yard stick is the Bravo. Might as well pick an ASD18 for comparison to the Bravo.

And once again the ASD8 is shorter than a #6 Speedmaster also, less weight and less cost.

If the Bravo is your yard stick then why are you looking at a much larger drive from Arneson? The Bravo is rated at what 600 lbs of torque?

Why would someone put a 16" Drop Box on a diesel application? The ASD8 in line is half the price and does the same job?

Sorry, but look at the pic again. Those are my trim cylinders on the boat. It was rigged new with those drives.

1st the wedge is only needed if the transom angle exceeds installation parameters.
2nd Why an ASD 8? Your replacing a Bravo right? If you had any kind of engine that could break an ASD 6, it would literally incinerate a Bravo drive. Thats why the Bravo replacement kit comes with an ASD 6 drive and you can still take the ASD 6 up a notch with the upgraded version.:p
