new drive from IMCO
 

anyone have any info on the new out drive from Imco thats suppposed to be stronger than anything out right now. not to start rumors but heard from a good source that IMCO has a new drive they are testing that may be the key to big power, something completely redesigned. hope this is not :bsflag:

i also heard from a good source that imco is, but wont release any details.

supposedly its a newer version of the scx drive with a -4 lower and a raised cav plate. A true surface drive. I cant wait!!!

From a friend at Desert Storm:

Someone please tell me that it bolts on without any modifications in place of my current Bravo One XR Sportmaster! Then please tell me it will handle 1000 hp. Oh, please only tell me this if it is true. Fingers crossed! :drink:

It looks like my SCX upper with a modified cav plate...therefore...with a helmet change...it would bolt your current transom assembly.

I run about 1040 hp through my SCX upper/ SC lower combo...and have yet to break it.

The lower looks like a shortened SCX lower (-4")...which is much stronger than a SC lower.

looks sweeeet!!! hopefully they can have some ready soon. Im getting tired of blowing propshafts on my sc lower. the scx uppers work flawlessly for me with 1300hp so im sure the new scx lower will also be able to handle some big hp. Its about time!!!

What props bolt up to it?

There are 2 options with the scx lower, a #6 drive propshaft or a 1 7/16 shaft that accepts the square bore bravo style props. Looks like imco really did their homework on this new drive.

Looks very promissing and I like that it can come with either shaft option... although if you're looking for something like this the 6 shaft probably makes the most sense.

One question, since this appears to basically be a surface drive, how large of a prop will it accept?

I have been told that they will accept up to an 18 inch diameter #6 prop

The gearcase diameter looks really big...

Does it draw water or do you need pickups?

Are these uppers available yet ?

wow, it certainly looks pretty cool.:drink:

Should be a great drive for super high x dimensions. Not sure how it would work with a single vee, but I guess with the right setup, anything is possible.

I dont doubt its strength though.

In addition to that, does the drive have a twin-pinion/downshaft to handle the higher side loading of a surface prop?

Reminds me of the NXT.

I've had my issues with IMCO in years past but it looks like they put together a nice package.

Dave at Imco said not available yet , still in the works, on paper?

Looks Awesome! I almost decided to go with the arneson conversion but now I have to wait.

Hopefully you all agree...? To get me, and others, to buy the "IMCO SCX SURFACE DRIVE" the price needs to be very close to the orginal scx. Not like the scx is pocket change for most bravo users! but....

Priced around $13800 for a upper and lower.

Priced under $20,000 If it comes with a complete transom assemblie, steering, extension box, trim, etc.

If there is much difference IMO the arneson is still a stronger, better, overall package. For a guy like me who could sell thier hydraulic steering, stand off boxes, transom assemblies etc. The arneson price is not that bad. Plus it WILL outlast all those moving parts in the scx, Gain speed, etc.

We also have to remember another reason why the price is very important because you will need to add on a extra $10,000++++ for props and to dial in the surface drive.

I also find it funny how so many people are "scared" to buy the arneson drive. IMO its because they can not afford it. I can't either, but I am saving. Most say something like, "If RIK could show me a boat like mine he has done". Well I look at it as ALL newer more powerful boats have surface drives. The #6, NXT, M8, INDY, bpm, arneson, Everyone who has more money then us "bravo" guys run a surface drive. They obviously are more efficient, faster, etc.

So if IMCO makes this happen at a fair price I doubt people will be saying, "well I might just go with the regular SCX becasue the SURFACE SCX is not proven on my hull yet"!

Very excited stuff!

I told everyone to wait

Wow, the same slow SCX with a 3" shortie what again is new about this?

The new part...... It will allow customers to install the SCX resulting in a higher propeller shaft height. Allowing them to get the case out of the water. In my boats case my bravo set up was standard lower with 1.5" spacer. The standard SCX is -2. So with my set up I can go up 3.5 inches. If this was not my stock set up then I would have to raise my extension boxes(rerig) to use them.

Your hero cookie is in the mail! :lolhit:

Funny no one else noticed but the upper drive is NOT the same as the SCX upper. It might share some parts but looks like a completely different case. Obviously the lower is different. It does look like it will bolt onto a bravo style trans assembly like the scx.

Could someone post pics of the scx next to the "surface scx".

Thanks

Its a new drive 4inch shorty made for #6 props and it is a new upper and lower. They are testing the drive as we speak and will not release much info. i know that they said it will be around the same price as the scx drive now.

Nice to hear that it might be the same price as the current scx, and that its a complete new drive.

Thinking about it more it really is not that much of a better deal then arneson bravo conversion even at that price.

For example:

Arneson "LISTS" about $24,000 ea. (could pay less)
Includes Drive, stand off box, hydraulic steering, Trim, Transmission, transom assemblie, etc.
Needs $5000 #6 prop ea.
Can sell to recover $2-4,000 ea side my stellings boxes, transom ass, hydraulic steering, etc.
Now ALL parts on the back of my boat are NEW and TIGHT, much safer when running over 100mph!

SCX Surface Drive $13,800 (on OSO) $15,000 (on IMCO)
Includes upper and lower drive
Needs $1500 IMCO forged Gimbal ring, Helmet, fluid resovoir, $5,000 in #6 style props
Nothing left to sell just stuck with 10 year old worn out parts

Looking at $1,000-$4000 +or- difference per side. All the new parts, the proven design, less moving parts, and prob more speed increase make the arneson the winner.

I was just getting so excited since my boat currently has no drives after breaking my SC's for the last time. Been saving for the Arneson but not there yet. Could afford the SCX but only because I could use my props. Untill I added this up the new SCX surface drive was exciting me but I am back to saving my spare change. I am still excited new products are coming out which is great for our powerboat industry.

I am surprised this thread died so fast? I guess I was the only one who got excited! No new info? Pics? Comments?

I heard at least 2 months...........

Yep, I also would like to know more about this Drive. I want to remove my Bravo's ASAP.

Are you shearing off prop shafts? Max machine worx has a insane billet prop shaft for bravo style lowers, I am running one a step weaker than their best one and I'm not breaking it with over1000 ft lbs of tq, mine was about 400$, there super billet one was about twice as much and they say it will easily take 1500 ft lbs. What kinda life are you getting from the merc lower gears in your sc's? Smitty

Nice!!!! Keep the info coming!!

Looks cool, hope it works, still like the Arneson.

+1 :drink:

This is the slowest moving thread I have ever followed on OSO! I guess everyones bravo must be holding up so good they do not get excited about this new drive! Normally OSO is the first on the net to have news, and I have never been the first to post anything!

IMO

80% NEW drive NOT a scx with a 4" shorty

The comment about the HUGE gears makes me think those are new also!

Talk about the larger cone clutch, could be the same as the scx could be even stronger

Higher HP rating then the SCX!

Sounds like imco is on the right track lets hope the Price is affordable!

Maybe it is the economy or that bolting on a surface drive without a lot a R&D may not be a sure fire success? :cool:

.

Nice looking drive. I bet it aint gonna be cheap...

The internal components are not
different than the SCX.

How do you know this?

Obviously the vertical shaft must be different?!

With a completely new lower case are you sure the internals are the same?

Completely new upper case, sure every part is the same?

We will find out soon when they release more info.

I agree this drive is a "sister version" and shares many parts but I do not believe its an original SCX with just a 4" shorty like "Most" people have been saying.

You are correct...the upper is the same internally as an SCX...but with a modified location of the cavitation plate to accommodate the larger diameter #6 props.

The lower uses the same gears as the SCX lower, but has a 2 inch shorter case and a 2" shorter vertical shaft....it also has the long skeg that is optional on the normal SCX lower.

This should be a great piece!

Chris,

You seem to have the inside scoop on this, any idea on price?
