Basics of How To Winterize jet ski watercraft. Remember this is general information, always consult a service manual for
complete info or your dealer.
1. remove fuel or fill up 2. check inside engine compartment 3. wash wax and remove water 4. blow-out ski 4 or 5 times and
after the final blow out, be sure to fog motor.. Feel free to view these active forums about winterizing your ski at pwctoday
1- You can empty your tank completely or Go to the gas station and fill your ski up with fresh gas, making sure you are at least
above 3/4 full, (want to avoid condensation in tank this way). Now add a fuel stabilizer, add it at gas station, now drive home,
this will help "slosh it" around and mix it on the short drive home.
2. This is also a good chance for you to look over the ski well, look for damaged hoses, check to be sure clamps are tight, look
for wear items, brackets, and things that may be damaged, loose or worn... from a year of riding things get loose or
damaged..... check over bottom of hull from underneath it, also look for frayed electric wires around the engine, burned/melting
wires, check the hose and clamps on your gas tank, Open fuse box and make sure nothing looks wet or damaged in there and
seal is good, give it a light coat of silicone grease,etc. Give a good wipe down with a silicone lubricant on your front engine
hatch rubber seal and on your rubber seal on the bottom of the seat also...
3. Now, wash, dry and wax ski, do a full detail, dry out inside of hull, you can use a shop vac if need be, or just towels, suck out
the small amount of water in the hose attachment where you hook up the water hose also.
4.- The next day, or a couple hours later on that day, blow out water again..it should have be done 3-4 times total from when
you rinsed out engine until your done winterizing it. As long as you give an hour or two break between each blow out to avoid
over heating engine. An hour or so later do another final blow out, on the final blow out you should raise the front of your ski as
high as you can when clearing water from the engine, this helps get it all out. Remember to not run engine for longer than
10-15 seconds each time.
65. remove the hose that goes from the air filter box to the engine at the engine side. now spray the engine fogging oil into it
for 5 seconds, then start engine for 10 seconds at idle only. shut off, re-connect engine hose. Inaddition Good idea to pour a
tablespoon or two in each spark plug hole.
6- Now remove battery from ski and put on trickle charger, if you don't want to use a trickle charger, then disconnect battery
cables and leave it in craft until spring, but the charger really is a good idea, and a VERY good idea if your storage time is more
than 2-3 months.
7. now spray a engine/hull/hose protection over all exterior surfaces in your engine compartment, like a silicone lubricant,
spray it over everything inside the hull.
9-now put seat back on, use a small folded over towel to prop up the back of the seat a inch for added ventilation. stor
10- cover ski with cover and your done. I don't use or suggest anti freeze on four strokes properly winterized. It's not required,
when you properly do everything else above including the 3-4 blow outs of water, which you MUST do. I know of no confirmed
cases where a 4 stroke engine cracked from winter, and the Yamaha manuals make no mention of adding antifreeze either,
and if it was required, or there was a risk of engine damage, YOU COULD BET YAMAHA would have it in the manual in big bold
words, but it's not there. AGAIN, the key is to blow out the water 3-4 times, which removes most of the water.
