1000hp drive
 

Hi, looking for advice on upgrading my drive. I will be running 994hp dyno'd horsepower and need a drive upgrade. Any suggestions. I was steering towards the IMCO SCX with built in hydraulic steeering stabilzers. However open to suggestions from those whith experience in this subject. Also anyone know of any good deals out there? Thanks:readinghelp:

What boat are you running? Twins or single? Weight, etc.

running a 30' Campion Chase 910 weighing in at 5800lbs dry weight. single engine.:eek:

#6 :)

yepp!

Arneson.

Yepp!

Didn't think the 910 came as a single drive option. Well, you learn something new every day.

Go with something strong. Arneson.

Thanks for the info guys, do you know or recommend any place specific to start searching for a good deal?

try westcoast performance. they specialize in this stuff

I perfer the SCX.. Well at least I bought one, and have not gotten the boat finished to run it yet. I will be in the same area on HP.. weigh about the same as you. 28' Checkmate. Single.. with power adder.

What price range would I be looking at? I would need the complete unit gimble mount to drive.

:poopoo:Wow they dont give those Arneson's away. Alittle to pricey for my pockets. Don't get me wrong I would love to have this set up!

When its all said and done, there really is no price difference when you factor the proven reliability .. Arneson is the real deal. Drive a few boats before you purchase if possible. A single application will be hard to find. Miami will have some twins.

I will agree with Mr.Gadgets on the SCX. I haven't busted mine with a 900 blower motor. :)

There is no such thing as 1000hp drive and a deal. If you get something cheap or used and save money up front, it will cost you more down the road. Compared to a #6 set up, the Arneson is a reasonable alternative. If I remember correctly the SCX runs in the $15k range and you are still running a Bravo style set up. Blow that once, and an Arneson would be cheaper.

Arneson

I'm running a #6 in a single engine v bottom application and have never regretted going this route.

while I agree with your assessment Tom, some boats just are not suited to a single arnie drive. Ever try backing a single engine surface drive cat into a dock ? :) Not to mention the lack of "trim ability" with no leverage to push the nose up and the less than stellar low speed ( on plane) handling. It does however make for a great "top end" boat. BTDT. Went back to a bravo style ( SCX) set up for a more all around ride.
Now, a single engine cat with a power splitter and TWO arnie 6 drives would be a sweet set up. I considered it for a while but WOW. the bucks involved would have been astronomical for a 25 foot boat.

Diamiond perfromance quoted me $13500 plus $900 for the helmet. I am just looking at all angles and yes I realize there are no deals when it comes to quality and reliability.:drink:

call steve at stern drive connections in Orillia. Local IMCO dealer and a great guy to do business with.

Try to find someone that has broke an Arneson ASD8, guys that race them don't even bring spare drives!

Can you run an SCX, sure but look at the big picture.

-You will still have to be "easy" on that SCX drive, the Arneson will out live the boat.

-How many hours before the SCX has to be re-freshed? An oil change is all you will need with an ASD8

-SCX will cost you some power and speed. My friend had his ASD8's off the boat and we could effortlessly spin the input shaft with our fingers...amazing efficient!

-It may cost you more upfront, but it will be worry free. Plus there is nothing cooler than a 40 ft tall rooster tail!

thanks guys, I really like the idea of the arneson and rooster tail at 100mph:eek: I hear that these arneson are very hard to come by used, I was steering in that direction to try and save some money.............................

thanks air packer I will give him a shout!!

Buy the boat just for the drives! Problem solved and cheap too! Not sure how to check them out to see what condition they are in, but if everyone is correct in that they last forever, then this is the route you want to take.

now there is an idea, Just wondering if the drives are any good? I would only need one of them and maybe re-furbish the other and sell it?

Those are ASD6 drives I think, but yea that is the idea!

A friend bought a 1984 Hustler Ferrara rigged ASD6 boat just for the drives.

What would be the difference between the 6 and the 8

Hard to tell from the photo, I am judging on size. You should post a picture of the ad on here and ask for the drive to be identified.

this chart shows that the A6 is only good for 550hp:(

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:hitit:

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.
