Proper preparation is essential for successful long-term jet ski storage, preventing costly repairs and ensuring your PWC is ready for your next adventure. The process involves several critical steps that protect your engine, cooling system, and overall watercraft condition.
Start with engine preparation by running your jet ski to operating temperature, then adding fuel stabilizer to prevent fuel degradation. For extended storage, consider draining the fuel system completely or filling the tank with fresh fuel and stabilizer, then running the engine to circulate treated fuel throughout the system.
Cooling system maintenance is crucial, especially for jet ski water storage in freezing climates. Flush the cooling system thoroughly with fresh water to remove salt, sand, and debris that cause corrosion. Ensure all water is removed from the cooling system to prevent freeze damage.
Battery care involves removing the battery and storing it in a cool, dry place with a battery tender, or connecting a tender directly if your storage unit has electrical outlets. This prevents sulfation and extends battery life during storage periods.
Clean the hull thoroughly and apply appropriate protectants to prevent UV damage and corrosion. Use a breathable watercraft cover to prevent dust accumulation while allowing air circulation. Finally, document your preparation process and store all maintenance records with your jet ski for easy reference when retrieving your watercraft.
