125 is time for a rebuild. A fresh Seadoo engine should be at 150 psi.

right if it's 125 time to rebuild, just make sure your holding the throttle wide open when you test it makes a difference.

I've heard that before but was wondering why?

If you leave the butterflies closed differences between cylinders in the carbs might make a difference in the compression numbers. If you open the butterflies you remove that potential difference from the equation.
