what is this part and is it important?

hey guys. me and my buddy have a 95 and 96 xp. mine is the 96 with the 800 and his is the 95 with the 720. we noticed on both at the back of the seadoo where the tow hook is, there is a small little nozzle (pee hole) that shoots water out of it. we then noticed on his, it will not shoot water through it. we traced the line and found it ran back into the engine and was hooked up but would not shoot water.
what does this do and is it important? thanks

That little discharge hole is there to verify that the pump is circulating water at high rpm. If you take it out on the water and ride at moderate speed, you will notice that a little water will squirt out, and it will be warm water if the engine is a operating temperature.
