Where can I find parts for my 1996 seadoo XP?

I'm purchasing my uncle's 1996 XP it isn't running but my uncle has told me it needs an electrical box and a gearbox(which I've never heard of in a seadoo). Any idea on pricing or a possible website?|||i use sbtontheweb.com they are in ca but will ship any where in the world.you can also use greenhulk.net it is a forum so you can get even more help with your ski. you can find people parting out skis that will sell those parts for a good price.
