Welcome aboard, you found the best SeaDoo site.
Snoop around the site, you will find a lot of answers; if not ask away, there are people out here that can help you through about anything SeaDoo ... and other stuff too.
Get maintenance manuals, you can find them on line or on this site as premium member. The manuals are very good.
Check threads here regarding fuel lines and cleaning up fuel system in general, especially if skis have been stored for a while or you do not know the history. You will find in your research here that lean running is the largest problem in lunching 2-stroke engines and about any leak or obstruction in the fuel system will cause lean running.
Have fun, quite a few Florida folks here.
