Hi, We just bought a 1995 seadoo bombardier xp (717cc)

This is the first PWC we have ever owned, when we took ownership it had a full tank of fuel, so we have had a couple of rides on it, how ever it was traded in at a car yard and they were unsure if it needs a fuel oil mix or if it is still standard and has seperate lines for both, i was wondering how to find this out, also if it does use a mix what is the ratio do i need to use?
When we bought it we were lucky enough to buy a warranty for it as it was from a car yard so i will not need to do repairs or servicing (as they need to be done by a marine mechanic) but is there anything i need to check to makesure it wont breakdown on me. Also the ski didnt come with an owners manual/guide so if any one has one that they could copy and email to me or a link where i can view or download one it would be great as i have tried to find one on the net but havn't found it anywhere
