SCX on IMCO Transom assy or ITS
 

So I wanna run an SCX on a 800-1000hp single . My first choice is to use an ITS strictly because of how clean they look assuming the SCX helmet does fit in an ITS assembly . My second option is to use the IMCO transom assembly . Not as clean but still doesn't require anymore holes in the transom . Whats your thoughts ?

don,t take this to the bank but i think the scx helmit will fit on the its transom assembly.i bet if you call imco they have the answer.

My SCX drives appear to fit right up to the Mercury transom assemblies.

You can do either, with the helmet chnage it will fit on both. Check the gimble ring though, the imco hp gimble ring is much beefier than the merc one. If you get a used its, its worth the extra $$ for that piece of mind.

The ITS does look clean, but it isn't as effective as an actual extension box. So really, you'd be putting it on just for looks. IMCO does make an SCX helmet for the ITS. If you want an extension box, put an IMCO on. I would do the IMCO transom assembly with the steering rams built in because it uses beefier parts than the mercury. I think the ITS on a single actually looks too clean, almost naked. Just my .02

Yea I already have the SCX helmet that I was going to use in an HP assembly . Hopefully it's the same the ITS takes . I'll call imco to verify i guess. I know the ITS is 6" of extension verse the 12" of the IMCO but I don't think I'm gonna need that extra . And yes if I go with the ITS it will be a new unit so I'll be the first to abuse it .
I get what your saying about too clean but that is going to go perfect with the clean minimalist style I'm trying to achieve with this boat build .

So far If ITS is used go with new or upgraded ring . IMCO is stronger and box is longer but not as clean . And SCX helmet should work in ITS .

As i said, the helmet for the scx will bolt straight in on an its, but consider the additional weight of the drive on the gimble ring. the imco ring is heavier and will support the drive better. ITS boxes are an 7 inch set back and the additional helmet and scx upper will add an inch as well for a total of 8.

Call IMCO and talk to Fred, but if I remember correctly the heavy duty gimble ring from IMCO won't fit on the ITS system. If your ring is a little questionable then I think you'll have to get a replacement from Merc.

OSD is right - You can run an SCX with a helmet change.

I run an ITS's on both my 21 and my 27, no doubt they are rock solid pieces - thing is here - they are theoretically built to handle 600HP.

You are theoretically way over the ITS 's rating, but no doubt its a solid piece.

The whole imco kit would be more stout, but for sure uglier.

I think the helmet for the ITS is different than the helmet for a standard transom assembly. They have different part numbers. But call and ask IMCO.

You can run a Imco helmet on an ITS set up but you can not run a Imco Gimbal Ring. The steering rams connect directly to the Merc ITS Gimbal Ring, Imco does not offer a gimbal ring that the steering rams connect directly to. As far as strength, I am told the Imco is stronger but the only failures in Super Vee Class racing have been Standard Bravo HP Gimbals and the Imco setup. Snowy Mountain Brewery, that never lost a race in 3 years, ran an ITS. The JD Byryder Fountain also ran a ITS with no failures. I am currently building a SV Race Boat and am using the ITS. If you are building a pleasure boat with that kind of power, I would feel comfortable with the ITS!

I have the ITS set up with the IMCO helmets and ITS gimbal rings and it has been a great package. Before I did the SCX conversions, I blew up three Xr drives in as many years. (running 700 hp/side) I did the conversion and went 5 years with out a problem. Last summer I finally locked one up into drive and had to have it rebuilt. Not sure why it let go but it was getting harder and harder to shift and I though it was a linkage issue (I had a few other previous linkage issues) My mistake for not catching it sooner I guess but the other drive looked damn near brand new when we went through it.

Thanks for the input . I'm gonna go with the ITS . Mercury has an availability date of March 15 so hopefully I'll be able to get one then . Can somebody help me find a picture of a SCX on a ITS ?

Im thinking about a ITS myself.. If you are putting it on 25' or less I'd go ITS, Longer or Cat I would go Imco

You know the snowy mountain SVL 29 has the ITS and Brian Forhan drives it like he stole it every time he's behind the wheel . Last time I saw the boat it had over 800hp and was running 125 mph

What is Mercury charging for a new ITS now? I was last told around $8300. I have 2 ITS's fresh from rebuild by Collabella Performance (Mercury Racing's Lake X Drive Builder) and I only need one. These are complete rebuild to racing standard for my Super Vee Boat. If you are interested I will sell one complete ITS for $4500 plus shipping!
Let me know if you're interested.

On Stellings^^^ --------------------------------------------------------In the AIR ^^^ LOL

777offshore I sent you a text . Quinlan that's just showing off lol ! Ive seen several SCX's. I just wanted to see how bulky they look on the ITS . I just don't want that Bmax look that looks like a sender block bolted on a transom .

Take a look at this thread here. Theres a couple pics of the SCX on the ITS (on a twin). I don't think it looks out of place like a big bmax.
