doesnt start

i picked up a 89 seadoo from a guy and have started working on it and i noticed that another 89 only had one carb, should this motor have two carbs, and where do i hook the water hose when i attempt to start it out of the water.

1988 XP will not start.. Need Help please i am new to working on a skii but this thing was basically a gift to me. I have been working on it for a while now and i just cant get it to start. It has spark (new NGK's) and it sounds like its wanting to start but somthing just wont let it...
