4.5 stock at sea level. Without limiting boost, at sea level, it will produce as much as 7psi. Could just have 2 computers, one high hp, one 87 octane ready.

Dustin

Without changing the cam you will need more boost for the same horsepower, which will shorten the life of the engine.
There is a reason why Merc uses a different cam on the 700 SCI

Biggest advantage is you can keep your smartcraft computer and the guardian on a 600, even on an upgraded 600 when reprogrammed properly

If you ever used the vessel view or system view Race Edition you do not want to miss all the information anymore
On the 600 the boost is controlled by ECM , so you can reduce boost at cruising RPM which saves fuel and helps your Bravo Drives

Yes, if you want more than 675hp, you'll need a cam change or intercooler change. As I said, I have cam and pulleys in stock.

Dustin

How much HP does your reprogram make?

Thanks for the info, Dustin and everyone. I've been wanting to know this stuff about the 600sci since it first came out. Looks like it is a pretty good all-around package with aftermarket help :D

Dustin

Do you already have a reprogramm for the 600 SCI PCM Module that works with or without a bigger cam and more boost or do you exchange the smartcraft system to a MEFI system like you do on the Mercury Racing 525 EFI Whipple Kit and loose smartcraft monitoring and guardian systems ?
If yes please show some Dyno results

We do not install a MEFI system like the SC system. Smartcraft and guardian systems work just like before. People can email me for dyno results.

Hey guys,

Just finished testing my PR 42 with Dustin's stage II kit for the 600sci and was blown away. With stage 1 I picked up 4 mph and was expecting maybe another 4 mph with the second stage which would have put me at 108 mph with Bravos...........was I shocked when I saw it hit 111mph in a relatively short distance with 2 aboard! As a matter of fact I didn't even play with the trim and found out it was actually tucked in a bit. With the same 6 blade Hering props I went 100mph stock, 104 Stage I and 111mph Stage II. Dustin's sh*t works!!

stage 1 ecu reprogram?

stage 2 ecu cam and pully?

which 42 pr do u have?

600sci Stage II = Reprogramed PCM + Innercooler water re-route + smaller pulley.

I just picked up between 9 and 10 mph with this upgrade!
My boat was consistantly doing between 80 and 82 mph, and now it is doing between 90 and 92 mph.
The picture below was my first pass after the Stage II upgrade.
I went faster (91.6 mph) with another prop, but was so excited, I forgot to take a picture of it.


Thankyou Dustin ! :ernaehrung004:

Here's a pic

I did a cam change as well......sounds like a different engine now

Your boat is stunning!

I have not done the cam change yet. My motor only has about 40 hours on it, and just went out of warranty in febuary.

I was planning on doing the cam at the first rebuild, in a couple of years.
Did you put in the 700 cams?

What did your mechanic charge for the cam swap.. per engine?

I only have one.

Chris

Here is a picture of my boat.
28ft Nordic Heat - Open bow
I still have 5 kids at home.

I am spinning a Hering 27, 5 blade bravo prop to about 5700rpm, with an IMCO SC drive. Slip is at about 6.7%

Chris

so u r the one who beat me to it!!! looked at it last spring i think right before the miami show... then poof it was sold

Sorry Dreamer

Had a big poker run/race down here in the Islands right after the boat show and my Doug Wright wasn't quite ready at the time.......got a hell of a deal so I couldn't pass it up.

Thanks CB

My cams were actually 500EFI cams which are a little more aggressive than the 700EFI cams......a few friends and I installed the kits over a weekend. We ended up taking the top end off the engines while keeping them in the boat.....not that bad as long as you have someone who knows what they're doing and follow all of the torque specs, etc.

yup it was a good deal... the sales person i was dealing with didnt even know it sold... i called her told her and she confirmed it when she got into work the next day....

Thats pretty stout increase!!:drink:

Thats awesome info!!

Is that Fountain's in-house paintwork? Beautiful!!
