Now that your carburetors are exposed turn on your engine and start spraying your fogging oil onto each cylinder.
Spray water on the soap to wash it away and try to collect the residue in a bucket to avoid causing any contamination in your yard.
Once your break has passed, turn the engine on for another 30 seconds, take a break, then rerun the engine. here
If you need a video for that to make everything clear here is a great video for de-winterizing your jet ski [links]
The first step of winterization is to flush your jet ski to make sure there is no debris or saltwater in the cooling system and the exhaust system
If your ski has the carbon type drive shaft seal (as opposed to the older style sealed carrier bearing driveshaft seal, normally anything older than 1996), running time should be kept to a minimum to avoid overheating the carbon seal despite having cooling water for the engine and exhaust. To avoid overheating the carbon seal. [links]
Now let’s go into the details of winterizing, Its look like a lot of things to do but believe me you can do as fast as 30 min, and the equipment that you will buy you will be able to use for the next winter, the first time is the hardest then it will be easy.
Disconnect your battery so you will be able to use it for the next session, however, you should plug it to a battery charger so it will stay in good conditions. and I find it good to write the name of the jet ski model on the battery so you won’t mix between the batteries if you have more than one watercraft or even some other batteries from another machine. here
Flushing your jet ski is really important watercraft uses an open-loop cooling system to cool the engine and the exhaust system, whats mean the jet ski will use the water of the lack or the beach to cool the engine and the exhaust system, so whatever is there in the water will go inside the engine to cool it (sand, small debris…etc), so when you flush your jet ski you are flushing all the water from the leak or the beach out that my content some debris with fresh water, and that will keep your engine clean.
It is just as important to (de)winterize your jet ski or summerize the waverunner after it has sat for many months over the winter. This is true for simple 2 stroke skis as well as new 4 stroke muscle craft. By doing proper maintenance to your watercraft, this will ensure that it runs top-notch in the summer not leaving you stranded on the lake.
If you have a 4 stroke ski, and didn’t change your oil in the fall, now would be the time to change your oil. You will need an oil extractor, but this will pay for itself after one use. Make sure to change your filter as well. If you have a 2 stroke ski, you are in luck and can skip this step as you are injecting your oil, or have mixed gas. more
Next use fogging oil and do the same for the choke lever if equipped both on the lever as well as on the carburetors. more
Fogging oil will protect your cylinders through a long storage season. First, you will need to remove the spark plugs. After removing them, spray fogging oil per the directions in each cylinder as well as through the carburetor. Next, replace the spark plugs and crank the motor. This will give some extra protection to the motor with lubrication throughout the winter season. more
To winterize a jet ski that won’t start, first remove the spark plugs and spray fogging oil. Next use gravity to force RV antifreeze into the cooling system. After that, spray fogging oil in the carburetor and move the PTO driveshaft. After this is complete, replace the spark plugs and you have a winterized ski.
To manually crank your motor, remove the spark plugs and turn the PTO driveshaft by hand or with some pliers. This will get the motor moving to distribute the antifreeze. here
In this step, you will want to remove as much water as possible. This can help by cranking your engine to remove water that is in the system, or by using an air compressor to push water through from the exit nozzle or your freshwater flush hookup. You will never want to use excessive psi while doing this, just start with a small amount. Gravity can be your friend depending on the ski, so nose up or down may help.
