How do you winterize jet-skis?

Question

i have a 1995 seadoo sp and a 1991 stand up ski and was wondering how i would go about winterizing them myself rather than payin alot of $$ to get it done.

Answer 1

if your engine have a carburators (which im sure they do) go to your local marina and ask for a can of " fogging" , it will come in a can with a spray nozel (about 8$ per can, u need 1 per jet ski)

remove airbox covering carbs while jet ski is running (leave jet-ski on trailer and back in water but DO NOT unload jet ski, you need water to keep engine cool) spray fogging into each carb until can is completly empty (engine should start to produce a heavy white or grey smoke, dont worry that is just fogging burning thruogh the engine) once can is empty shut off engine and pull out of water and let ALL WATER  drain out of engine and jet ski (dont forget to put airbox back on). if your jet ski is a 4 stroke change motor oil. also buy a bottle of fuel stableizer (about 5$) and dump into fuel tank if you have any fuel left , remove each spark plug and dump about a tablespoon of 2 stroke oil into each cyclinder, s***w spark plugs back in , then turn the engine over as to make sure the cylinder walls get covered with oil completely (do this by cranking the start key while the kill switch is activated so the engine does not start) take out battery (s) ,then you are done and your jet ski is winterized,  

fogging is a thick gell that when sprayed into carbs puts a film through the engine to protect the internal parts from rusting

total cost is under 20$ for fogging , fuel stabelizer and2 cycle engine oil. if you keep you jet skis in a heated garage you do not need to winterize but it cant hurt any either.  if you are keeping them outside if they have covers for them put them on then buy a cheap tarp at home depot (10$) and put that over them also and you should be good until spring

good luck
