This is great info for 600 SCI owners. I have been considering the Stage 1 upgrade, all depends on what is found wrong with the starboard engine today/tomorrow. No oil pressure, went from hero to zero in the blink of an eye. Hopefully something that has to do with the oil pick up or oil pump. Engine was rebuilt by previous owner 65 hrs on it, 230 hrs over all. If the engine needs rebuilt was considering 700 cams and Whipple program. Anyone done that mod.? If engine checks ok was going to throw Stage 1 at it.
Did you see this in the swap shop?

What is your boat, drives, set-up, etc? I am completely stock 600 SCIs, rebuilt XRs/Sportmasters and ITS. My cautious side says not too much extra HP for the XRs

I have a Howard Sportdeck 600 sci. I have switched to the Imco scx upper with the SC lower. 1.5 ratio. I have ran the boat with the stock 600... stage2... stage 4...
You are right to be concerned about the drive. I have gone through 3 drives but have 475 hours on motor. Motor was rebuild and tuned to a stage 4 whipple last year. With my old Max Machine XR it ran over 100mph. With the new SCX I have not ran it real hard yet, handling is good but it seems slower. It is also difficult to tell because testing in Lake Havasu in August is usually 110 degrees with a water temp about urine point six degrees. I have had it at 94-95 with the SCX but have not really tried for top speed. Maybe the speed will still be there... I hope.
