Summer has arrived, and it’s time to prepare your beloved Ski-Doo snowmobile for its seasonal slumber. Proper summer snowmobile storage is essential to prevent damage, prolong its lifespan, and ensure it’s ready to conquer the snow once winter returns. This step-by-step guide provides everything you need, from cleaning to pre-season preparation. By following this checklist, you’ll keep your Ski-Doo in pristine condition while safeguarding its performance.
What should you do to prepare your snowmobile for storage?
Here’s what you’ll need for the process:
• High-quality fuel stabilizer
• Storage oil (fogging oil)
• Chaincase oil and appropriate lubricants
• Battery maintainer
• Breathable snowmobile cover
• Cleaning supplies (e.g., mild detergent, microfiber cloths)
• Essential tools and your Ski-Doo owner's manual
Make sure your workspace is clean, organized, and well-lit. Having all supplies ready will make the process quick and efficient.
Step 1: Thorough Cleaning and Inspection
Washing Your Snowmobile
Start by washing your sled thoroughly. Pay attention to hard-to-reach areas like the undercarriage where grime accumulates. Removing dirt, mud, or salt will prevent corrosion over time. For best results, use a mild detergent and a soft brush. When finished, ensure the snowmobile is completely dry to prevent moisture-related damage.
Inspecting for Wear or Damage
Conduct a detailed inspection of your snowmobile. Look for cracking, leaks, or loose parts, especially in critical areas like the suspension or engine mountings. Repair or replace damaged components now to avoid surprises next winter.
Pro Tip: Take note of parts that may require early service during pre-season checks.
Step 2: Fuel System Preparation
Fuel can degrade and clog your system during long periods of inactivity. You have two main options for managing fuel during storage:
Option 1: Add a Fuel Stabilizer
If leaving fuel in the tank, add a fuel stabilizer to prevent sediment buildup and preserve fuel quality. Run the engine for a few minutes after adding the stabilizer to ensure it circulates through the fuel lines.
Option 2: Drain the Fuel
For storage longer than a few months, draining the fuel system is a more reliable solution. Make sure to remove all residue from the tank and fuel system components. On carbureted models, drain the carburetor bowls; on fuel-injected models, refer to the owner’s manual for detailed instructions.
Which is better? Use stabilizers for convenience during shorter storage periods, and drain the fuel for prolonged off-seasons.
Step 3: Engine and Lubrication Maintenance
Change Engine Oil and Filter
For 4-stroke engines, replace the oil and oil filter before storage. This protects the engine from harmful contaminants that could cause damage over time. Oil Change Kits offered at your local Ski-Doo dealer make it easy with everything you need all in one box. Your dealer can also perform this service if preferred.

Use Fogging Oil
One critical part of understanding how to summerize a snowmobile is applying fogging oil. Remove the spark plugs and spray fogging oil into each cylinder for a few seconds. Rotate the engine by hand to distribute the oil evenly across internal components, preventing rust and corrosion.
Grease Components and Replace Chaincase Oil
Lubricate:
• Suspension Fittings (e.g., A-arms, shocks)
• Steering Linkages
• Axle Bearings
Drain and replace the chaincase oil as outlined in your Ski-Doo’s maintenance schedule. Always use recommended lubricants for best results. Additionally, spray any exposed metal components with a corrosion inhibitor for added protection.
Step 4: Battery Maintenance
Disconnect and Clean the Battery
Disconnect the negative terminal first, then the positive. Wipe the terminals clean with a wire brush to prevent corrosion. Store the battery in a cool, dry place away from moisture or extreme heat.
Use a Battery Maintainer
Connect the battery to a trickle charger or maintainer to keep it optimally charged throughout the summer. Neglected batteries lose capacity and develop sulfation, reducing their lifespan.
Pro Tip: Label the storage date to keep track of battery health over time.
Step 5: Track and Suspension Care
Loosen Track Tension
Reduce the tension on the track to prevent unnecessary stress on suspension components and to avoid stretching.
Elevate the Sled
Lift the snowmobile’s rear and place it on a stand so the track is off the ground. This alleviates pressure on both the suspension and the track, keeping them in better condition.
Lubricate Suspension Parts
Grease all pivot points and shocks to ensure they remain rust-free and function smoothly next season.
