Probably similar to the full SCX standard length, somewhere in the mid $13k range depending on where you are shopping.

Any new information out there on this?

the ring angle in relation to the cav and prop shaft look weird to me

Or even the relationship of the gimbal ring to the transom plate.

the ring looks cocked out at the lower pin.

still waiting for info!!!!!

Yes yes

pic of the actual new surface drive from imco
 

its a -4 with scx upper and a new lower thats not as bulky as the scx lower. i just got this pic yesterday. sorry but no tech details yet. heard imco is just starting to test it with the new lower.

having trouble posting pic
 

someone send me there email and i will sent the picture so someone else can post the pic. sorry guys

picture emailed
 

thanks

surface drive pic need help
 

i have a pic i would like to post. someone else please send me their email address to send pic. im unable to post it here. need a little help thx

Never got a pic buddy....

new drive looks pretty bad-a$$

Looks like it has a spacer on it to clear the big wheel. Funny...I have been asking IMCO for 2 yrs about an improved lower for the SCX...and Dave acted like there was nothing in the works. Lower looks lots faster than the Anvil we have on our SCX. However, we sent them to Wilson Performance and got huge improvements.

Do you have any photos of your lowers modified by the Wilsons?

That drive looks pretty sweet!! I imagine it is going to have a sweet price tag too.......

Damn, that lower looks ALOT better than the original.

Too bad it isnt an SCX.... It clearly says SCT on the case.

I cant imagine that it would cost THAT much more than the standard SCX, which rings in right around $13k.

I was planning on getting an SCX/SC this winter, might have to wait a little while longer to hear about this a bit more.

I do...but the pics dont do it justice. I spoke with Craig and he said that in 30 yrs he has not seen a set of lowers in such piss poor "off shelf shape" as what we sent him. They shaved a significant amount off of leading edge as well as bullet... will send pics tomorrow. The new lower in the pic looks much faster than the original SCX lower...cav plate is much different too. It would be nice to know if the new lower will bolt to orig SCX upper.

Lista boxes very nice.

chris, thanks for posting the pic!
also heard bmax has a new drive. had a friend that spotted a newer bmax drive at lake of the ozarks 2 weekends ago. sorry no info on it, but dont think its a surface drive.

I'd like to see the scx lowers that are redone as well.

Surprised how many people have not read the entire thread??!

The SCT has been out for a while, it is the sister drive to the SCX minus the cone clutch to shift, instead it uses a transmission.

The new drive from imco that this thread is about currently has no name. I like to call it the SCX/SCT SURFACE drive.

Its NOT just a lower that is ment to bolt on to a existing upper.

Only good pic I have. What I can tell you is that when they came from IMCO it looked like pot metal...and there was no leading edge anywhere to be found. They are now a true satin finish...and have defined leading edge as well as less mass.

Whats your prop shaft depth in relation to the hull in this pic?

1.25" above bottom of hull with spacer on. Spacer is comming off...will be 2.25" above.

Looks alittle big at the nose,guessing bigger gears in the lower?????

I dont believe that anyone has called it just a lower that bolts onto an existing upper. Obviously it wouldnt work, at least not with a #6 prop, as there would be no clearance.

Now, the combo that was just posted appears to be an SCT upper and a modified, much more hydrodynamical efficient lower. Since the SCX and the SCT use the same lower, it stands to reason that this could potentially bolt up to a standard SCX upper, which many people with SCX/SC combos would be glad to see happen considering that the current SCX lower is a bloated mess.

The upper is a scx or sct. I may be running these new drives on the galdiator. They have not tested the new lower but it is going on there hallet 44 with 1100,s. The boat has sct,s on it that is why this upper says sct. The drive is 4" shorter with the larger scx gear set. If this works well it will be the ticket.

The upper is different from the standard sct.

The upper is totally different because the lower has a new bolt patern

Yes....and bigger gears, shafts in upper as well.

hydrodynamical ? cant be better than the other Imco lower,or the Merc speedmaster foots?

The Current SCX lower is NOT as hydrodynamic as any of the lowers you referenced. However, Wilson did do an awesome job on blueprinting and trueing them up...if you run them at a high x-dim, like we do on our 42ex..then you mitigate some of the issues with their size. There is no doubt that straight from IMCO that you will lose speed with the SCX lowers...but with some work you can get most of it back..and have the reliability as well.

I think people are confusing the drives, the sc and the sct has been out for a while, the scx came out just over a year ago, the new one is just being or just has been released. from what i gather the new one is a surface style drive similar to a black-hawk or 6 just no counter rotating and based on bravo style gears.

As for the scx lower, and maybe Wilson can answer this question. On a boat where the drives need to be lower will one lose as much speed with the scx lower or by using the sc with a billet shaft will be about the same?

They tested the drive today ith great results

Killer what HP are they rated for?

Just to clear up confusion....? Did they test some type of version of a new "surface drive" based off a SCX or SCT. Does not matter which one just as long as its the new Surface style drive which is what this thread is about.

Glad to hear they had good results!

This is one confusing thread.

In my opinion it has the same internals as a standard SCX. It looks like they just changed the case to make it shorter and to give more prop clearance. The upper part of the upper, the gear tower if you will, doesnt look different at all, just everything beneath it has been shortened.

The lower case does not look like it will bolt up to a standard SCX, because I can see an 8 bolt pattern instead of 6. I bet dollars to doughnuts that it still uses the exact same gears as the normal SCX lower, the bloated monster. However if any gears were redesigned, it is probably in the lower, if only to make it a little smaller.

So i place my bets on same exact gears in both the SCX and SCT, shortened shafts to account for a -4 length, and modified cases for both halves.

Just my guess, time will tell. And until someone from Imco comes on here and says otherwise, this is still where my money is.
