Options include color, (silver, black) propshaft 1 1/4" or 1 7/16" Hub comes with it.
You will need a new helmet, reservoir, and the drive. If your motor won't idle down to around 800rpm.. you can install a shift interupter switch.
Thats about it. Like I said they are looking at the ITS trim indicator at this time. They should have something in the near future.. You will probably have to use their Gimbal ring to accomadate the trim sender setup?? Not a bad idea to install their HD gimbal ring..
Hope that helps.

No problem the 600s idle at 700 I will have to use the merc gimbal ring because the steering connects to it with the ITS setup. Got mechanical trim indicators so if the electric ones don't work not a big problem. I like the idea of using #6 props so I can stop throwing the bravo ones. This boat has a 22 1/2 X dimension which has the props surfacing.

+1 on the ITS with Mechanical trim sender.

Do they (IMCO) have an ITS specific Gimbal ring?

I would want to stick with Bravo Props due to cost. Makes it much more palatable to keep multiple sets for different conditions. Aren't the SSM props for surface piercing drives only?

I ordered my SCX upper today through MrGadgets. I am going to mate it to my SC lower. I cant wait to see what this thing looks like. :evilb:

Mr Gadgets 10-31-2009 03:36 PM

2112,
They are working on a way to use the trim stuff that Merc has on the ITS. Not sure if they will end up with a special Gimbal ring or not. They just started looking at it this past week.
The idea is to run the SCX lower, it is -2".. Getting close to surfacing on some boats, maybe. If that is the case the less of the lower in the water the better.
But the Hub that comes with the 1 7/16 shaft will fit the Bravo props with the square hub. So you pop out the Merc hub and slide in the Imco one and on to the new lower..
Lot of options to fit what ever might be the case.

Mudslide,
Not sure what the #6 prop uses for shaft and spline. I will have to check and see. I try to stay away from those expensive props, so I have no experience with them.

Nice Airpacker!! Makes me want one also.. :)

Why cant I see the picture of the SCX... all I see is a small white box with a red x in it?

Dick,

My main concerns with the ITS are the Tie bar attachments (I would like to use my MM, center to center bar) being able to use my existing 2" short sportmaster bottom and replacing the final weak link, the stock ITS Gimbal ring.

My next concern is if there is any affect on handling due to the extra 150 lbs way out back?

If you are interested Mud, I can shoot you a price, just pm me.

Dick,

Imco offers the #6 shaft for a option with the SCX lower.
01-3446 Prop Shaft #6 Prop Shaft #6 $766.00
The reason I want these props because my boat likes to throw Bravos and it is not from running in big water. I run mainly in rivers and small lakes. Not the great lakes. So thats why I want #6 props already throw 5 6 blade bravos (3 Herings and 2 Throttle Ups) thats not cheap either. Bravos aren't made to be surfacing props.

I see that in my price list Bob, a difference of $124.00 list. I will check to see what the cost is to step up to them.

They also have the option for silver instead of black. I went with this option so the SCX upper matches the SC lower. Looks great. I have run this set up for one season, running same speed as the Teaque did. I have had no problems.

DiamondPerformance 11-03-2009 04:28 PM

NWCP, How much power do you have in your Fountain?

NWPC 11-03-2009 07:33 PM

I am running a single 575sci. I have gone thru 2 xr's and 2 Teaque platinum's before landing with the SCX. So far I am very happy with the results and looks.

Dino 11-04-2009 05:33 PM

I have a full season on them. 39 cig top gun 775 Zuls. I was amazed how well they shifted, I thought it was going to be an issue. Running Scx uppers, SC lowers, no speed loss. They are awsome!!

What RPM do you shift at? Do you use interrupters?

I am assuming no ITS?

Dino 11-07-2009 05:14 AM

Shifting about 850 plus/min, Yes/ ITS with staggered set up, no interrupters, Torco synthetic trans fluid (per Imco). The boat seems to like the little extra weight in the azz with both Herings and Bravo props.

I just had a GT500 rear axle customized and gear swapped and the rear end specialist said "no Torco, No warranty". He preferred the mineral base though.

My big concerns are the strength of the stock Gimbal and how the weight will affect my boat. I think we have nearly the same hull but I am a bit lighter up front.

PS I am a fan of Neill's too. He built my boat for me. Do you know if he is doing good?

PSS My Fords will idle at 850 but shifting often kills them which is a pain. They stay running at 1000, any lower and I have to play a game to fast shift to keep them running. That is pretty much what I always end up doing. I have EFI inductions waiting in the wings just for this problem. They won't be ready for 2010 though.

I would think the shift interupter kit would be the answer to your shifting problem..

I am anxious to hear what you find out about the upgrade Gimbal ring.

Does the SCX lowers have a water pickup or do you need a transom pickup?
