While you enjoy jet ski joyride, you also need to ensure that it runs perfectly next time. That’s why you need to winterize a jet ski for the next season. Follow the below-mentioned steps to winterize your jet ski.

Step 1: Flush the jet ski by using freshwater and do this for about 3 minutes.

Step 2: Disconnect the water hose and let your jet ski have a couple of blips on the throttle to discard any leftover water from the exhaust system.

Step 3: Add the fuel stabilizer. Double-check the bottle as well as the fuel level of the jet ski to ensure that you’re filling enough fuel.

Step 4: Ideally, you should fill up the jet ski’s fuel level all the way up, especially if you’re storing it outside. This will help your jet ski to prevent any condensation build up in the tank.

Step 5: Carefully remove the air intake pipe of the jet ski from the throttle body. Check your jet ski’s model and follow the guidelines on how to remove the air intake pipe according to the user manual.

Step 6: Then start up the jet ski and put some fogging oil into the throttle body. Continue doing this until the jet ski starts to cut out or when it releases a white smoke from the exhaust.

Step 7: Carefully disconnect the spark plugs and stick coils. Do not start any work if there’s still power going through your jet ski. This might cause accidents and damage to your jet ski.

Step 8: Use the fogging oil again and apply it to the jet ski’s cylinders. Squeeze each cylinder for at least 3 seconds.

Step 9: Return the spark plugs and stick coils inside the unit. Make sure that they are attached securely and not loose.

Step 10: Open the throttle and start cranking over to the jet ski. Do this for a couple of times every few seconds.

Step 11: You will need to remove the battery. Taking out the battery will help preserve the jet ski’s battery life. Store the battery somewhere where it’s not freezing or at a low temperature.

Step 12: Spray the engine with an anti-corrosive lubricant spray to get rid of any excess water from the engine bay. Excess water can mess up the quality of your jet ski and might attract rust as well. Make sure that there’s no excess water left before proceeding to the last step.

Step 13: Then, start running your coolant through the exhaust system until it starts to appear at the pump end. Ensure to follow the advised set-up for the bilge pump, which is powered by an external battery. Again the bilge pump set-up might vary depending on the type of jet ski model you have. Be sure to verify before starting with your set-up.

FAQs – Frequently asked questions

  1. When to winterize your jet ski?

Ideally, it’s best to winterize your jet ski when the temperatures drop to 25 degrees Fahrenheit. It will be a huge help if you’re up to date with your local weather news. Be alert when the temperature reaches below 30 degrees Fahrenheit.

  1. Why do you need to winterize your jet ski?

One main reason is to protect the jet ski’s engine. The fuel used for jet ski is more susceptible to moisture. It has a tendency to absorb any condensation that takes place on the inside of the fuel tank that usually forms when there’s a drastic or sudden change with temperature.

During the summer season, the fuel can absorb at least 0.5% of moisture. This triggers the ethanol to disengage with the gasoline forming an ethanol-water mixture. This combination is quite lethal to your engine and is the number one cause for corrosion and lethan.

Once this mixture starts to build up, it’s going to eat away the aluminum tanks. It will also strip the anodizing off the sides of the tank. Gasoline also decomposes and oxidizes over time. This can form into nasty deposits that can harden and smell like varnish.

  1. Does it cost a lot to winterize the jet ski?

If you’re planning to DIY the whole process, then you might need to prepare at least 200$ for the total cost.

That’s if you know how to do the whole process. You may also seek help from a family member or some friends.
