This is an Update video on the process I use to winterize my current jet ski. I did a video on my 2-stroke Yamaha a few years ago, and since I now have an stx12f, figured I would do an update video. Original Video: • How I WINTERIZE my JET... `

I'm picking up a 12f next week and this video was amazingly helpful. Even just getting a decent look into the engine bay has helped a lot. Thanks!

[@jonathanharrington1464]

Great video! You pointed out things that I've never thought about doing!

[@madmanmechanic8847]

I do Marine repair for a living I love the practical simple steps you did on the video I am not a ski tech just mainly boats. I would how ever would of like to seen how to change the oil and filter. GREAT JOB SIR!

[@NoNonsenseKnowHow]

Thanks man glad you found it helpful. Oil and filter on these is pretty simple. Just pump the oil out from the dipstick tube and screw off screw on the oil filter

[@madmanmechanic8847]

@@NoNonsenseKnowHow I watched another video on and oil change , I have only worked on a few skis one time some older Yamahas . I like your straight forward type of videos just give it to me straight . I like that shit. Don't change a thing . Where do you get your oil filters and what is the number on it. Can I get Wix? If you ever need any tech advice on any boats please hit me up be glad to help out if I can.

[@NoNonsenseKnowHow]

Cool, thanks man. And I usually just try and get the OEM filters

[@madmanmechanic8847]

@@NoNonsenseKnowHow My Marine business too a dump so I really need this job coming up on the ski. Have a good one bud! Nice talking with you!

[@NoNonsenseKnowHow]

Damn, sorry to hear that. If you're a marine guy, you probably know of the old Chrysler outboards right? What do you think of them? I have an old 100 horsepower and have done three videos on the boat so far. A lot of people say they are junk, but the thing has ran flawlessly so far with basically no maintenance. And great chatting as well.

When pulling the spark plug wires off (as one person said in a comment) he puts the plug wires onto the metal posts. Those posts are there for a reason. If the plug wires are just laying there "not grounded" out, there's a chance of blowing the ignition module. The spark needs to go somewhere when cranking the engine over. Meaning, either leave the spark plugs attached to each wire. But they have to be grounded. Or use the grounding posts. If your afraid of causing a fire from the spark, that means you have a fuel leak somewhere. Use the grounding posts as one person said. That way the spark is going to ground and there's no chance of damaging ignition components. $$$

[@NoNonsenseKnowHow]

Did I fail to mention the metal posts in the video? I thought I did. The newer jet skis do not have them. I usually ground mine out with little jumper cables I have or lay them on the engine casing with the plugs in boots and that give them a ground path. Is that that what I showed in the video? Should have went over it in more detail in the video. Yes it is possible to damage and ignition coil or module without a ground. very rare though.

[@nometalgearr]

Thanks for the video. It's fun to watch them :)

[@clarencewiles963]

Thumbs up 👍 water is a issue 😊

[@zsqtina]

Hi! Thanks for the great video! Is it possible to go through this process while the jet ski is on a slip at the marina? We don’t have a trailer to tow it away to winterize it. The main concern is when the antifreeze comes out from the back how we can catch it without getting any to the river

[@NoNonsenseKnowHow]

Yes I suppose it could be done at a slip if your marina says they're okay with it. If you use marine RV antifreeze, it's okay for it to get in the water and is non-toxic

[@NoNonsenseKnowHow]

And no problem, glad you found the video useful

[@robertmeyer2804]

Ty good video

[@the40735]

My 1998 stx 1100 has the posts to put the spark plug wires on.

[@NoNonsenseKnowHow]

Sweet! Yeah that's a nice thing to have. Makes total sense. My Sea-Doo used to have them

[@the40735]

@@NoNonsenseKnowHow I don't know why kawasaki did away with them once the stx1100 was changed to the 12 and 15f

[@NoNonsenseKnowHow]

@@the40735 yeah I'm not sure either. Maybe it's a different coil type they use now.

I've had issues with when putting gas in the tank at the gas station - it seems to pressurize the tank and after a short while of filling the tank - the air acts like it can't get out and when it pressurizes enough all of a sudden a bunch of gas in the neck blows out.. then the process continues as I fill... fill .. pressure.. gas blow out.. until I get it full. .. anyone else having this issue?

[@NoNonsenseKnowHow]

Yes my stx12f has always done the same exact thing. So I just feel it on the slow click

[@NoNonsenseKnowHow]

Seems to be a design flaw to me. Unless somebody else can chime in on here

[@buzzie8]

Do you need to run engine until it is warmed up before running RV anti freeze? Thanks!

[@NoNonsenseKnowHow]

No. These don't have a thermostat

[@biancadelacruz7010]

Engine has been over heating on my STX 12F, do you have any tips or videos to troubleshoot?

[@NoNonsenseKnowHow]

No, I haven't personally had that problem yet. Do you run your jet ski in the salt water? I've heard of cooling passages getting restriction from corrosion. Also make sure to check that you're getting good water flow and at the intake hoses not clogged

[@brienjones121]

Did you get antifreeze to come out the side port where water circulates ? I got antifreeze out the back but never pumping out the side port, worried their could be water in there.

[@NoNonsenseKnowHow]

If I remember right yes some came out when I revved the engine. But I wouldn't worry about that. That's just a hose that leads up there. I'm going to be winterizing mine pretty soon so I can let you know for sure

[@cwatson42785]

Hey great video! First time ski owner and getting an idea for winterizing process. Hey could I spray everything down with silicone spray? Like everything in the engine bay and on and around everything at the jet assembly? Thanks again for the video, helped allot!

[@NoNonsenseKnowHow]

Yeah you could. I would avoid getting it on hoses and wires though. Biggest thing is just make sure to cycle some antifreeze into the engine. And no problem!

Getting one this weekend from my uncle broken! Can I reach out to you for some help and guidance? Have mechanical experience but never with marine machines.

[@NoNonsenseKnowHow]

That's awesome. Honestly there are probably a ton of really helpful videos on here with lots of useful diagnostic tips. You should be able to get it figured out pretty easy. Mechanical and Marine counting all the same stuff. Good luck on it and let me know how you make out!

@@NoNonsenseKnowHow I see info online but not much for this model. I know for starter the dash is broken, and forget that I don't want to spend $500+ for a replacement, I can't even find one for sale.

[@NoNonsenseKnowHow]

Yeah that's one of the biggest problems with these skis. The parts are very expensive and can be hard to get

[@aidanmartel2488]

How long did it take from the time you started the antifreeze and the time you shut it off? I ran a lot of antifreeze (5 or so gallons) through mine and couldn't get it to come out of the exhaust.

[@NoNonsenseKnowHow]

I would say probably 30 seconds before it was coming out of the exhaust. That's with revving the engine a couple times though
