You can upgrade the gears in the A6...

HD Gear Upgrade for ASD6/1721 Drive Units:

Upgrade the power rating of your ASD6/1721 drive unit with our New HD gear upgrade.

Available in 1.32:1 and 1.56:1 ratio's, the gear up grade increases the power rating to over 750 lbs of torque.

There is also an A7

Look at the latest specs...

thanks Omerta one but I will be runnig about 916.3 FTLBS of torque at 5400 rpms. I doubt it will last or will it?

The A7 goes to 850; best ask Rik.

Dam...if you were running 916.2 ft lbs, it would probably work...j/k

I would either tame down your motor build, or go with the Arneson. In the long run, it will be worth it. Baby'in that 1000HP mill aint no fun, and thats what you will have to do with a bravo style drive. Dont forget a beefy tranny too.

Im not sure, but i would think a wet sump #6 would rob more HP than the arneson, and probably be slower?

your right mild thunder it will be no mercy

We can change the gears out and it will handle the power.

If you want speed and rooster tail call Rik and order a new arneson, and be done with it! Very cool set up.

Want value call Dick "mr gadgets" and order a scx. Its the strongest so called "bravo style" out there but there isnt much "bravo" about it! I have personally seen his badass checkmate and very powerful engine fire up. If he trust a scx and builds drives then you should also!

If you want to realize how good those two options are you could price a x-power at $35,000!

This looks like a deal! One to use one to sell

Hello Campionchase910:

Well Mr. Gadgets started off in the right direction but you did not give us enough information on what your trying to do.

1. Is this a Bravo set-up boat...I assume it is but want to make sure.

2. It is single engine right.

3. V-Bottom or Cat.

You can run a SCX/SC drive on your boat they have a complete assembly in the classified section of this site. The SCX can handle your HP/Torque specs. easily.

I know as I have personal experience with this set-up and your type of ratings on the engine side of the equation. The SCX/SC combo is the best set-up versus a SCX/SCX combination. Why! well the full SCX drive scrubs waaaay to much speed on the top end.

Now the down side to the SCX/SC combo is that the weak link will be your lower i.e...the SC unit namely the gear sets. If you fly the boat or jack rabbit your starts your lower will not live. If you get past 4.5K RPM and roll into it... the drive will give you the speed your looking for and be reliable.

No one touched on this but the beauty also with this combination is your not bound by cleaver props. The cleavers in a single engine application will kill you in terms of cost. Why! because you need to find the right one to work on you boat and that is not easy or cheap. The SCX will allow you to run Bravo style props and they are far cheaper and more plentiful than cleaver props.

If you are already budget concious than the SCX is the way to go IMO in a single engine boat. Now if you change one fact i.e...your boat is a twin than I would save your duckets for a set of Arnesons.

KAP
P.S. If you do choose the surface drive send me a P.M. I have three single engine cleavers for sale. I have run both a surface drive and a Bravo and I am currently using a SCX/SC combo by choice not due to cost.

kap do you think if you had a twin cat and you ran a higher x dimension where you could get the SCX lower bullet out of the water it would perform efficiently? I would think that then you would have to use the 6 props to keep from breaking them. I think Nordic did one of their big cats with this set up. Haven't heard how it performed.
