Maintaining a jet ski (personal watercraft, or PWC) ensures its performance, reliability, and longevity. Proper maintenance helps prevent mechanical issues and ensures your safety while enjoying your time on the water.

Here are essential tips for maintaining a jet ski…

Regular Maintenance Tasks

1. Read the Owner’s Manual
   • Familiarize yourself with the specific maintenance schedule, recommendations, and procedures outlined by the manufacturer.
2. Inspect Before Each Use
   • Before each outing, conduct a visual inspection of the jet ski:
     • Check for any signs of damage or wear on the hull, intake grate, and ride plate.
     • Inspect the fuel system, including lines and connections, for leaks or damage.
     • Ensure the engine compartment is clean and free of debris.
     • Verify that safety equipment, such as the lanyard kill switch and fire extinguisher, are in place and functional.
3. Flush After Use
   • After riding in saltwater or contaminated water, flush the jet ski’s engine with fresh water. This helps remove salt, sand, and debris that can damage the engine and other components.
4. Engine Maintenance
   • Change the engine oil and oil filter as recommended by the manufacturer.
   • Check and replace spark plugs according to the maintenance schedule.
   • Inspect the air filter and clean or replace it as needed.
5. Fuel System
   • Use clean, fresh fuel and ensure the fuel tank is properly vented and sealed.
   • Add a fuel stabilizer if the jet ski will be stored for an extended period to prevent fuel degradation.
6. Battery Care
   • Monitor the battery charge regularly, especially if the jet ski is not used frequently.
   • Clean battery terminals and connections to prevent corrosion.
7. Hull and Exterior
   • After each use, wash the jet ski with fresh water to remove salt, sand, and other contaminants.
   • Apply wax or protective coatings to the hull to maintain its appearance and protect against UV damage.
8. Trailer Maintenance
   • Inspect and maintain the jet ski trailer, including tires, bearings, lights, and hitch components.
   • Ensure the trailer is properly secured and maintained for safe transportation.

Seasonal and Periodic Maintenance

• Winterization – If storing the jet ski for the winter, follow proper winterization procedures, including draining water from the engine, fogging the cylinders, and stabilizing the fuel.
• Professional Servicing – Periodically, take the jet ski to a certified mechanic or dealership for thorough inspection, servicing, and any necessary repairs.

Safety Considerations

• Always prioritize safety when maintaining and operating a jet ski. Use personal protective equipment (PPE) such as a life jacket, and follow all safety guidelines and regulations.

Regular maintenance is essential for keeping your jet ski in top condition and ensuring a safe and enjoyable experience on the water. By following these maintenance tips and adhering to the manufacturer’s recommendations, you can extend the life of your jet ski and minimize the risk of mechanical issues.
