Winterizing

[Alexander Sinclair]

I have a 1991 waverunner 3 and winter is coming in Canada. Could anyone help me out with what I should do to winterize mostly to get the water out so nothing freezes and cracks. I usually fog everything and put some gas stabilizer and give everything a shot of grease But don't want anything to freeze and crack. Any help would be appreciated thanks

Waverrunner 3s are winterized by unbolting the engine, pump and electronics and dropping it into a superjet

Flush the cooling lines with antifreeze, take out the battery, and you're good.

If you should already have a flush kit installed- you might consider a set up such as this. You might wish to use a RV type (alcohol based) antifreeze solution instead of ethylene glycol.

I'm still waiting for a picture to surface of a motor cracked from freezing.

Just run it dry and get the water blown out. I've stored my 2 strokes in Minnesota cold for years without an issue. Stabil in the gas tank, run it so it gets in the carbs. Probably want to use some fogging oil in the cylinders too.

Fire it up in the spring. I wouldn't worry about blowing out the cooling lines in a 2 stroke, but that's just me.

So i dont think it has a flushing spot. If it did where would it be I looked all over front and back of the motor and there is nothing in any of the hoses to flush it.

Add stabil to gas, Pull your flame arrestors, fire your ski up, spray fogging oil into carbs with engine running until you smoke the whole neighborhood out, and then if youre paranoid about freezing, pull cooling line off head and pour rv antifreeze into cylinder jackets. I usually skip the antifreeze and just make sure ive blown as much water out of the exhaust as possible. Once you get done with all that, pull your plugs and spray more fogging oil in plug holes to coat cylinder walls.

I would recommend to do it as Lumpy suggested. For your information, there was /is a way to flush- that was state of the art a quarter century ago: http://partsfinder.onlinemicrofiche...UNNER III 650 (8001001 AND UP) EXHAUST SYSTEM , see index 11 and 12. You take out the screw and washer and temporarily replace with the thingy pictured. It's 8mm.

Thanks a bunch that's super help full when you say blow as much water out the exhaust do you mean just start it and give it some shots till no water runs out the exhaust hole
