A friend of mine has 600SC's in his 51OL.... They just got rebuilt at about 200 hours.
Over the past couple years that he's owned the boat this is what I know.... 2nd season he had to replace the CMi headers, then rebuild one of the blowers, then one of the ECU's, then for some reason the engines wouldn't make boost and the belts were somehow slipping and a couple of outdrives and a partridge in a pear tree. He installed Teague drives and they haven't stood the test of time either but they may have been driver error....
When the engines were rebuilt they were in OK shape. He didn't need to do it but wanted to do it anyway and it's a good thing he did because one was about to drop a valve... Had it been started one more time it's possible the valve would have dropped...
The owner of this boat uses it EVERY weekend and maintains the boat with no expenses spared... He's had another 51OL before this with 575's, a 45 Sonic with 500efi's and bulldogs before that, a 35 Sonic before that..

Just ran my 42 PR this evening with a new ECU program for the 600sci and picked up 4 mph and much better acceleration. I hit the limiter at 5500 as I started playing with the trim and went into guardian so I'm sure with another 2" of pitch there's another 2 mph to be had. All in all a very cost effective upgrade.

that was from just a reprogram?map must be way off from the factory,or maybe it has a electronic wastegate that lets it build more boost?Impressive #'s!!!

Who's ECU upgrade are you using? That is a pretty impressive increase.
How is your Doug Wright running?

The DW 43 is finished and turned out to be a heck of a nice piece so it was worth the wait. Doing some mods to the rudder box and extension and should be testing again in a few weeks. Since I have to wait on that I also have Chief swapping out the blowers for some of the new magnesium 5.0 Whipples and MOACs.....you know how it is 2 hrs on the water and you already want more!!

I have cam and pulleys in stock. But reprogramming without cam/pulley is far easier than pulling that motor apart.

Does anyone know what the max boost on the 600 is if the computer isn't holding it back? It seems to me that a pulley and reprogram would be the way to go. I do like the fact that stock it is now rated for 87 octane. Just need a dual program--one for cruising/trips and one for high octane/boost max power
