How to Winterize a Yamaha Jetski

As the winter season approaches, it is essential to properly winterize your Yamaha Jetski to ensure its longevity and optimum performance in the upcoming summer. Winterizing your jetski involves a series of steps to protect it from the harsh elements and prevent any potential damage during the cold months. Here is a comprehensive guide on how to winterize your Yamaha Jetski:

1. Clean and inspect: Thoroughly clean the exterior of the jetski to remove any dirt, grime, or saltwater residue. Inspect the hull, engine, and other components for any signs of wear or damage.

2. Change the oil: Drain the old oil and replace it with fresh oil. This prevents any contaminants from sitting in the engine during the winter.

3. Stabilize fuel: Add a fuel stabilizer to the gas tank to prevent fuel degradation and keep the fuel system clean. Run the engine for a few minutes to allow the stabilized fuel to circulate.

4. Fog the engine: Spray fogging oil into the carburetors or spark plug holes to coat the internal engine components. This helps prevent corrosion and keeps the engine lubricated during the winter.

5. Drain the water: Remove the drain plugs and allow any remaining water to drain from the exhaust system, cooling system, and any other water compartments.

6. Remove the battery: Disconnect the battery and store it in a cool, dry place. Make sure to charge it periodically to maintain its charge level.

7. Lubricate moving parts: Apply a marine lubricant to the steering system, throttle, cables, and any other exposed moving parts to prevent rust and corrosion.

8. Seal the exhaust: Use exhaust plugs or tape to seal the exhaust outlet and prevent critters from nesting inside.

9. Cover it up: Invest in a quality cover to protect your jetski from dust, debris, and UV rays. Ensure the cover is properly secured to avoid any potential damage caused by wind.

Now, let’s address some common questions about winterizing a Yamaha Jetski:

1. Can I leave fuel in the tank during winterization?
It is recommended to add a fuel stabilizer and a full tank of gas to prevent condensation and fuel degradation.

2. How often should I charge the battery during winter storage?
It is advisable to charge the battery every 4-6 weeks to maintain its charge level.

3. Should I remove the spark plugs?
Removing the spark plugs and spraying fogging oil into the cylinders is a good practice to prevent corrosion.

4. Can I use regular engine oil for my Yamaha Jetski?
No, it is essential to use marine-grade oil specifically designed for personal watercraft engines.

5. Should I inflate the trailer tires?
It is recommended to inflate the trailer tires to the manufacturer’s recommended pressure to avoid flat spots.

6. Can I use a tarp instead of a cover?
While a tarp may provide some protection, it is best to invest in a cover specifically designed for jetskis, as it offers better fit and durability.

7. Is it necessary to winterize if I live in a warmer climate?
Even in warmer climates, it is advisable to winterize your jetski to prevent potential damage from unexpected cold weather.

8. Can I store my jetski outdoors during winter?
Storing your jetski indoors is the best option. However, if outdoor storage is the only choice, ensure it is properly covered and protected from the elements.

9. Should I flush the cooling system before winterization?
Yes, flushing the cooling system with fresh water after every use and especially before winterization helps remove any debris or saltwater residue.

10. Can I use antifreeze in the cooling system?
Using antifreeze is not necessary for personal watercraft since they are designed to drain all water from the cooling system.

11. Do I need to winterize if I plan on using my jetski occasionally during winter?
If you plan on using your jetski occasionally during winter, it is still a good idea to perform basic winterization steps to ensure its proper functioning.

Following these winterization steps and taking proper care of your Yamaha Jetski during the winter season will help prolong its lifespan and ensure a trouble-free experience when summer arrives. Remember, prevention is key when it comes to protecting your valuable watercraft.
