    So just got inside with bad news my 750 hull w a slx780 motor isn't getting water?? After bout 10 min of riding I am completely over heated and the water box sizzles when water touches it... I tried depressing the plastic valve by the clylinder heads and at first nothing then sporadic spurts of luke warm water?????? What should be my check list how do i make sure its getting water.....

    why do you think it is overheating? If water is coming out of it then it is most likely not tightened down. It's where you connect a garden hose so you can flush it after a day out.

    because the heads seem hot ... and water box/ muffler are SUPER hot (when water drips off me onto the water box it sizzles) and im pretty sure that it not supposed to be the case...... O and water only comes out when i hold the valve down w/ my finger.. and its not a whole lot of water, more like an intermittent trickle....

    Hot means you couldnt hold you hand on it for any length of time. Do you have a working MFD to display overheat? It sounds like its probably fine if you ask me, but it looks really beat.
