Hi.... I am buying a 2004 seadoo gtx supercharged but before I spend the money I want to do a compression test. What the compression should be?

Prob around 120-140 but will vary. The SC machines are lower compression because of the forced induction. Make sure to hold throttle to the pin when you do test, it shuts off fuel injectors this way. Biggest thing is over 100 and with 10 each so 115,120,110 is fine, 130, 100, 120 has issues.
