    It is not cavitating, it is porposing. This is very common on this model. I have a 97 750 ZXI does same thing. You can start by adjusting trim nose down that will help somewhat.
    Then you may need to install some trim tabs. This will help a great deal. What seems like cavitating is that the prop is still cranking @ high rpms when the ski is not hooked up. (out of the water). Good luck

    I've never heard of trim tabs on a JetSki. More down trim will help, shifting your weight or turning the handlebars slightly to one side can help. It is probably worse when the fuel tank is low.
