If the transmission is strong enough, then it will work. The new ASD8 has counter rotation built into it now, unlike the past, but the in-line drives will work fine also.

For a project that you are speaking of, this is the lowest cost means of doing the job. The in-line drives are less expensive than the drop box units, and the transmissions you speak of are not that expensive either.

I just do not know how strong they are.

I know that Express is using a ZF gear to do the same thing that you are thinking of, but the transmission has a Max RPM rating, (3,800 rpm) and a max HP rating. I believe they are over on both issues.

We need to contact Marc Berman/BAM to find out what the real story is on the planetary reduction/drop BW 5000 or 72C. Strong or weak…..

Hey Rik, did you guys get that Carrera together that you were putting the drive in? So, the counter-rotating props would cancel out any associate side torque if you used it in a single engine cat?

The Carrera was finished late last season, around Labor Day Weekend I believe. It ran 105 right off the bat. It's too cold to run now, but this summer with some different propellers it will hit the target 108. (1.56:1, 32” Pitch, 6,000)

I believe that the counter-rotating topic has to do with a triple engine installation.

The boat will definitely run more even with a counter-rotating engine, as the three engines, with serious torque, can influence the handling of a boat.

Has anyone else seen these photo's of this ASD6 Kit? http://www.arneson-industries.com/

The drive is on some kind of boat, don't know what, but it looks really cool!

Been running Arneson drives on my boats since 1983, 1721 up to asd-8 wouldnt have any other drive, buy far the fastest and strongest hands down but thats my point of veiw.

Rik,
I am one of the lucky performance boaters living close to San Rafael CA which is home town to Arneson-Industries. My boat is kept at the same marina where Howard launches his 46' Skater for testing. Quite often this allows me a chance to watch, listen and drool as the 4500hp Skater turbine runs 160mph + across San Pablo Bay. I use to think my 28' Scarab was cool but nothing is more humbling than to see Howards tow rig pull up and proceed to launch what looks like the F-15 fighter of boats. It is so cool to hear the turbine spooling up, I just stand there watching like a little kid and wishing for a ride.
OK back to reality... I have a tiny little malnurished 28' Scarab (4600lbs) and was wondering if an ASD-6 is enough for a 572" with 725 hp / 700 lbs? What are the upper limits of a beefed up ASD-6?
Thanks

Dear All

I Have Ads8 Arneson Drive With Crash Box
What Solution For Use This Drive With A Counter Rotation ?
Best Regards
