The thrill of summer jet skiing creates memories that last a lifetime, but when the season ends, many owners make costly mistakes that lead to engine damage, corroded parts, and disappointing spring surprises. Research from marine equipment manufacturers shows that nearly 40% of personal watercraft repairs could have been prevented with proper off-season preparation. At Party Barn Boat and RV Storage, we’ve seen firsthand how the right winterization approach transforms storage from a gamble into guaranteed protection for your valuable watercraft.
Your jet ski represents a significant investment in family fun and recreation, which makes proper storage preparation essential rather than optional. The good news is that with the right knowledge and a few hours of focused effort, you can ensure your personal watercraft emerges from storage in pristine condition, ready to deliver another season of excitement on the water.
Clean Thoroughly Before Storage
The first step in protecting your jet ski starts with a comprehensive cleaning that goes beyond surface-level aesthetics. Salt water, lake minerals, and accumulated grime contain corrosive elements that continue their damaging work throughout the storage period if left untreated. Use a marine-specific cleaner to wash the entire exterior, paying special attention to the pump intake and cooling system passages where debris tends to collect.
After the initial wash, inspect the hull for any cracks or damage that might worsen during storage. Small gelcoat repairs completed now prevent water intrusion and more extensive damage later. Don’t forget to clean the interior storage compartments where damp life jackets or forgotten towels can create mold and mildew problems over the winter months.
Flush and Stabilize the Engine System
Your jet ski’s engine requires specific attention to prevent internal corrosion and fuel system degradation. Start by flushing the cooling system with fresh water, which removes salt deposits and contaminants that accelerate corrosion. Most jet skis include a flush port that makes this process straightforward, though you should consult your owner’s manual for model-specific instructions.
Fuel stabilization protects your engine’s internal components from the gummy residue that untreated gasoline creates over time. Add a high-quality marine fuel stabilizer to a full tank of fresh gasoline, then run the engine for several minutes to circulate the treated fuel throughout the system. A full tank prevents condensation from forming on interior surfaces, which would introduce moisture into your fuel system.
Protect Electrical and Battery Systems
The electrical components in modern jet skis are sophisticated and sensitive to extended periods of inactivity. Remove the battery and store it in a climate-controlled environment where you can maintain a charge with a trickle charger throughout the storage period. This simple step extends battery life significantly and ensures reliable starting when spring arrives.
Spray electrical connections with a corrosion inhibitor designed for marine applications. These specialized products create a protective barrier against moisture and oxidation that would otherwise degrade connection quality and potentially create electrical gremlins next season.
Lubricate Moving Parts and Seal Openings
All moving parts benefit from fresh lubrication before storage. Apply marine-grade grease to steering components, throttle cables, and any other pivot points according to your manufacturer’s specifications. This protective layer prevents rust formation and keeps components moving smoothly.
Seal exhaust and intake openings with appropriate plugs or covers to prevent insects, rodents, and moisture from entering critical engine areas. These small invaders cause surprising amounts of damage when they nest in warm engine compartments during storage months.
Cover and Store Properly
A quality cover specifically designed for your jet ski model provides essential protection against dust, UV damage, and moisture accumulation. Ensure the cover fits snugly but allows for air circulation, which prevents condensation buildup underneath. Consider using moisture-absorbing products inside enclosed storage areas to maintain optimal humidity levels.
