Preparing Your Jet Ski for Off-Season Storage

Sep. 18 2024 News By Broward Motorsports Jupiter

Jet skis provide endless enjoyment during the riding season, but as the off-season approaches, proper storage is essential to ensure your watercraft stays in great shape. Failing to store it correctly could result in engine corrosion, fuel degradation, and more. This guide will walk you through the steps of preparing your jet ski for off-season storage, provide recommendations for products, and include tips to address common storage concerns.

Why Proper Storage Matters

Taking care of your jet ski before storing it helps extend its life and ensures it performs optimally when you’re ready to hit the water again. Poor storage practices can lead to:

  • Engine corrosion from trapped water or salt.

  • Fuel system damage due to untreated, old fuel.

  • Battery drain or degradation from lack of proper care.

By following the guidelines below, you’ll prevent costly repairs and get your jet ski ready for smooth sailing next season.

Thorough Cleaning and Inspection

Exterior Cleaning

  • Wash the Hull and Deck: Clean your jet ski with a mild, non-abrasive cleaner like Star brite Jet Ski Cleaner or XPS Personal Watercraft Products available at Broward Motorsports Jupiter. Focus on removing salt, grime, and algae buildup, especially around the hull and deck.

  • Clean the Jet Pump and Intake Grate: Use a small brush to remove debris from the intake grate and jet pump. This prevents clogs and corrosion over time.

Engine Flushing

  • Flush the Cooling System: Using a fresh water flush kit like Salt-Away Flush Kit helps remove salt and contaminants from the cooling system. Be sure to follow the manufacturer’s instructions to avoid damaging internal components.

Hull and Equipment Inspection

  • Check for Damage: Carefully inspect your jet ski’s hull for cracks or scratches. Also check the handlebars, seat, and other components for wear.

  • Service Recommendation: If you notice significant damage, schedule repairs with a professional to avoid bigger problems later.

Fuel System Preparation

Add Fuel Stabilizer

  • Prevent Fuel Degradation: Add a fuel stabilizer like STA-BIL Marine Formula to your tank to prevent fuel from breaking down and forming gum or varnish. Run the engine for a few minutes to circulate the treated fuel through the system.

Fill the Fuel Tank

  • Reduce Condensation: Keeping the fuel tank full during storage minimizes condensation, which can cause rust inside the tank.

Professional Services

Battery Care

Remove the Battery

  • Safe Disconnection: Carefully disconnect the battery by removing the negative terminal first, then the positive.

Battery Storage

  • Prevent Battery Drain: Store your battery in a cool, dry place. To maintain the battery's charge over time, use a battery maintainer like the NOCO GENIUS1 Fully-Automatic Smart Charger. This device prevents overcharging while keeping the battery in good condition.

Frequency of Maintenance

  • Regular Checks: If storing your jet ski for more than a few months, check the battery’s voltage every 30-60 days. For outdoor storage, consider charging it more frequently, as temperature fluctuations can drain the battery faster.

Lubrication of Moving Parts

Spray Lubricant

  • Protect Against Corrosion: Apply a marine-grade lubricant like WD-40 Specialist Water Resistant Spray to moving parts, including the steering and throttle cables. This prevents rust and keeps components moving smoothly.

Comprehensive Lubrication Service

  • Professional Lubrication: Some dealerships offer complete lubrication services, ensuring every part of your jet ski is treated and protected for long-term storage.

Engine Internal Protection

Use of Fogging Oil

  • Protect Internal Components: Spray fogging oil, such as Yamalube Fogging Oil, into the engine cylinders to prevent rust and corrosion. This is especially important if you’re storing your jet ski for several months.

Frequency of Maintenance

  • Annual Fogging: Engine fogging should be done at least once per year, especially if the jet ski is stored in colder, humid climates where corrosion is more likely.

Storage Environment

Choose the Right Location

  • Indoor vs. Outdoor Storage: Indoor storage in a dry, temperature-controlled space is ideal. If storing outdoors, use a storage shelter or cover to protect it from the elements.

Use a Quality Cover

  • Protection from the Elements: Choose a durable cover like the Classic Accessories StormPro Heavy-Duty Jet Ski Cover to protect your jet ski from UV rays, rain, and dust. Ensure the cover is breathable to avoid moisture buildup.

Secure Storage Solutions

  • Professional Storage: Many dealerships offer secure storage facilities, which provide a safe, climate-controlled environment for your jet ski.

Trailer Maintenance (If Applicable)

Inspect the Trailer

  • Tire and Bearing Checks: Check that the trailer tires are properly inflated and the bearings are well-greased. Inspect for any signs of rust or wear.

Professional Trailer Maintenance

  • Service Offered: A professional trailer service will ensure that your trailer is in optimal condition, ready to transport your jet ski for the next season.

Additional Tips

Remove Personal Items

  • Prevent Loss or Damage: Take out electronics, riding gear, and personal belongings to avoid theft, damage, or mold.

Documentation

  • Update Service Records: Keep a log of all maintenance and storage preparation done on your jet ski.

Insurance and Registration

  • Review Policies: Check your insurance and registration. In some cases, you might want to suspend coverage during the off-season, but check with your provider to ensure there’s no lapse in coverage.

FAQ: Common Questions About Jet Ski Storage

1. What if I’m storing my jet ski for an extended period?

  • If you’re planning to store your jet ski for more than six months, consider scheduling a mid-storage inspection. This can include battery maintenance and a check of the cover and storage conditions.

2. How should I store my jet ski in colder climates?

  • Winterization is crucial in colder climates. Be sure to add antifreeze to the cooling system and remove the battery for indoor storage. Additionally, fogging the engine becomes even more critical to prevent freezing damage.

3. Can I store my jet ski outside if I don’t have indoor space?

  • Yes, but you’ll need a high-quality cover and possibly an elevated storage platform to keep the jet ski off the ground. Regularly check the cover for damage and ensure it’s securely fastened.

4. Do I need to use a fuel stabilizer if I’m only storing my jet ski for a month or two?

  • Even for shorter storage periods, it’s a good idea to use a fuel stabilizer. Modern ethanol-blended fuels can degrade quickly, and stabilizer ensures that fuel remains fresh and clean.
