Essential Maintenance Tasks: Keeping it in Top Shape

Engine Maintenance: Regular maintenance will prevent unexpected break downs. Start with the basics: change your spark plugs according to the manufacturer's recommendations. Clean or replace the air filter to maintain optimal engine performance. Use a high-quality two-stroke oil, and be sure to use the correct mix. Check the cooling system for any blockages and ensure it’s operating efficiently. Regularly inspect the fuel lines for cracks and leaks. These steps will keep your engine running smoothly and extend its lifespan.
Jet Pump and Impeller: Inspect the jet pump for any damage or wear. Check the impeller for any dents or chips, as this can affect the ski's performance. If you notice any damage, consider replacing the impeller. Keep the jet pump well-lubricated to reduce friction and wear. Proper maintenance of the pump is critical for getting the most out of your ski.
Electrical System: Check the battery terminals for corrosion and clean them if necessary. Inspect the wiring for any damage or wear. Make sure the start/stop switch and the ignition system are working correctly. Maintaining the electrical system is essential for reliable starts and smooth operation.

Storage Tips: Preparing for the Off-Season

Proper storage is critical, especially when the riding season ends. Start by flushing the engine with fresh water to remove any salt or debris. Drain the fuel and add a fuel stabilizer to prevent the fuel from going stale. Lubricate the engine components. Remove the battery and store it in a cool, dry place, and consider giving it a trickle charge throughout the off-season. Cover the jet ski with a protective cover to keep it safe from the elements. By taking these steps, you can ensure that your SuperJet 650 is ready to go when the riding season begins. Preparing your ski for storage ensures a longer lifespan. Proper winterization protects your investment and prepares it for the next season.
