New Imco Dual Downshaft Lower Article is up!

[RiverDave]

If you get a chance take a look at it on the front page! Absolutely bad ass product! I see them doing very well with this in the future.

Nice article and good pictures. Are the lower gears still Mercury XR gears or does IMCO have someone making the gears for them now?

 

[Jonas Grumby]

I was with Freddy last week, he said they are imco gears, made from timkin steel like the scx upper.
But damn $9900. That’s a $25k bill to go full scx.

It's pretty disappointing that the drives in general are so delicate, even with all of the "upgrades" available. Coming from the jet and v-drive world, those drives are virtually bullet proof. Are Volvo drives any better?

 

[J DUNN]

I hate to be a nay sayer so I'll just say this.

I'd be MORE than willing to do some "testing" with my Brummett TT and see how well that drive does pushing my 240 tank around the lake at max RPM.

PS. not that their claiming it will handle what I could put through it, just saying I'm willing to be the first one to disintegrate it after sending the upper gears tumbling down into BOTH down shafts.

How do these compare to the current SCX 1400 lower? It looks like the gear case is slimmer?

That much if you purchased a new SCX with the new double shaft lower and not a retro-fit ?
I'm wondering what a speed comparison between a stock SCX and the one with the new lower would reveal ?
How much HP is lost due to increased frictional loss versus potential gain from redesigned gear case ?
Hopefully more testing and info will be revealed.

Friend of mine bought a jet boat put about 700 hp to it and twisted a shaft. Lol

New aq shaft, $300?

Thats what happens when you adapt an engine that was designed to propel a different type of vehicle (car engine) to use in a vessel with VERY dofferent design characteristics. The V or direct drive is the most similar adaptation but with their own sacrifices.....

Cool bit of machining. Doesn’t really address the problem though. The entire drive was never designed for the kind of power being thrown at it.

Im still not sure why everyone still sees the need to drag the entire gear case though the water when there are other proven options. If I had the need and the means, I’d take a real long look at the surface drive options.

Honestly to prototype and only make up ten of these on a first run? I thought 10k was pretty cheap?

My point is just whenever you use a form of propulsion that was designed for something else and adapt it to a different application there will be some substantial sacrifices to be made in either efficiency or durability.

We'll use a jet vs alternative for this example. The inherit design of the 2 leads to 1 being more efficient means of pushing a planning vessel but sacrifices durability and simplicity. The other is much more durable and simple, however it sacrifices efficiency to do so. Both of which are adaptions in order to use a car engine in a boat.

There are,many other differences obviously but i just listed the most basic for the sake of illustrating my point.

He going to sell a shitload more than 10, just like most his other products. And I’m sure the price won’t drop after the first 10.

 

[HST4ME]

10k is very reasonable.

 

[DrunkenSailor]

In comparison with a #6 drive this is cheap and you can buy one separate from the motor which can be hard to do from merc.

 

[J.P.]

It looks badass and glad to see there is another option.

 

[buck35]

So what ever happened to the weisman (sp) drive?
I've read they.worked so well they were banned from racing.

Having been in Mfg’ing my whole life.. to make short runs of these things like they are doing I can’t hardly believe they are able to make them that cheap and still have any kind of profit. 10k is nothing.

They will likely produce at 10/20 at a time at most. Compared to say Mercury who makes 100,000 at a time?

 

[twocents]

According to IMCO, the retail $9,900 price is what they intend to sell them for going forward. The first run of ten were primarily for testing and evaluation. There are a few of the original ten available for sale at the $9,900 price but it doesn't come anywhere near covering the initial investment made in developing and manufacturing the first ten. The production run of units (significantly higher quantity than ten) now in progress are scheduled to be available in late January or early February 2019.

I’m not suggesting imco is gouging, I just wish I could afford it,
