How fast can a 1996 seadoo gti jetski/pwc go?

I am considering buying a 1996 seadoo gti. It has a 720cc engine. I want something that can go fast and something that I won't get bored with but I do not need it to tow a tube or a water skier. If someone can just tell me weather or not the 720cc engine will have enough power and acceleration to keep me busy that would be great thanks!|||70mph stock
