Welcome aboard Indyfreak!
The best recommendation we can make is to upgrade your membership as a Premium Member. This gives you access to the shop manuals for your ride - your most fundamental source of information to service and repair your Seadoo. Your owner's manual lists the items to be serviced - the shop manual shows you HOW to do it with detailed diagrams and specs.
Of course the most important source of information is seadooforum.com! Check out the How To section of the PWC forum! Lots of DIY information that will help you get started on doing your own service and repair and save tons of $$$.
