    1999 Kawasaki 750 sxt - need help winterizing

    Can someone shoot me some pics or a link on what hose to pull to add antifreeze. I know how to fog the engine and etc just not sure where to add antifreeze as I'm starting the ski to pull through engine.


    EDIT- ITS AN STX MODEL and year 1998 not 1999

    if you look by the hose thats t'd to the head and pipe there is a rubber cap. Under the rubber cap is a brass fitting like a barbed fitting but not really the barbs and has threads on the inside. What is this?



    do you know whats this hose is inside here going to a pisser type fitting above the pump?

    The part with the rubber cap is the flush hose fitting. The part under the cap should be barbed, not threaded. The cap must be secured with a hose clamp in normal use. A 5/8 garden hose will fit on the fitting. And, as always, NEVER run the water unless the engine is running.

    Not sure what the hose is for. Could be a pisser, could be a drain hose for the battery vent, etc.

    So a regular garden hose fits over that brass nipple? There is threads on the inside for sure. Previous owner just ran the ski with no work gear clamp on the rubber boot.

    There red is one barb on the brass fitting but it's also threaded on the inside.


    Thanks for the help

    You need a clamp on the fitting cap.

    Your 750 motor is pretty much self draining, no need for antifreeze. Pull that boot/cap off of the flush fitting, and blow here with the air compressor while running the ski. Blip the throttle to blow water from exhaust. Fog, pull the battery, grease all cables, etc. Don't forget to add fuel stabilizer before you run it.

    Hard for me to tell from your pic, but I would bet the hose you show is either for your venturi bilge siphon, or an exit / drain cooling line.

    Thanks buddy!

    The hose shown in the last pic goes to a pisser type fitting above the pump on the hull to a brass fitting on the pipe

    A 5/8" garden hose--with the end cut off. Find an old hose that you ran over with the lawnmower and make use of it.

    The fitting may be threaded on the inside, I never noticed. I think one ring around the outside is right.
