    Winterize GP1300R

    I have been researching the correct way to winterize a 2003 GP1300R and found this so far:

    1) wash waverunner
    2) buy a pump and flush engine with antifreeze
    3) fill fuel tank and add fuel stabilizer
    4) lubricate the usual spots
    5) cover and put in garage for winter

    are there any steps that i am missing?
    do i need to add any oil stabilizer?
    any suggestions on where to get a pump?

    Thanks.

    -Steve

    I have heard good and bad things about putting antifreeze in the cooling lines, waterbox, etc. Is your garage attached to your house? Might not have to run antifreeze, just make sure you start the ski and blip the throttle a few times before you put it to rest for the winter.


    Most important tips to winterizing.


    Fog the motor very well. Use fogging oil and not WD-40.

    Get all the water out of the hull and leave the seat unlatched for ventilation.

    Spray inside of ski down with a can of Spray Silicone (again not WD-40)

    Fix any problems or plan to fix them before the next season starts.


    Good Luck!

    I get a heck of a deal for indoor storage (not heated) if they winterize my waverunner... anything special with the jetworks mod to tell them....

    Thanks for the info Mike. My garage is attached to my house, so maybe I don't need to flush with antifreeze. Does anybody else have an opinion on this for a ski being left in a garage in NJ for the winter?

    Pretty simple. If it can freeze then you need Antifreeze.

    is there really enough residual water anywhere that would cause any problems if it freezes?

    That is an argument that can go either way.

    I have a Yamaha Service department by my house that tells me they will never run antifreeze through a ski when they winterize because it is not in the Yamaha instructions and it can cause problems and is not needed. They also mentioned that there is not enough residual water in the system to cause any problems if it does freeze, as long as you start your ski up and get most of the water out. I am not saying they are correct, but this is what they told me. (Keep in mind this is the same shop that did my pump shoe recall and installed my intake grate bolts in the wrong holes.)

    I personally start my ski up many times throughout the winter months and keep it in a garage that is warm enough the water bottles I store in it do not freeze.

    So, my $.02 is, if its going to freeze where you store it you should run the antifreeze through it.

    For people who live in below freezing winter areas, where the ski will be in those below freezing areas

    YES YOU DO NEED TO WINTERIZE.

    I've read its better to RV Anti freeze (pink color) in the lines the regular auto mobile anti-freeze. Less corrosive i guess. I dont need to do it i store mine in warm storage all winter. I just fog the cylinders, Stabilize the remaining fuel, change the spark plugs, clean the hull. and then i'm done.
