1. Prep Your Storage Space
2. Add Fuel Stabilizer & Fog Your Engine
Ethanol fuel attracts moisture which can cause corrosion. Even fuel without ethanol can cause problems. Bottom line? If you let your gas tank sit all summer long filled with ethanol fuel and no stabilizer, you'll damage your engine. Pick up some Carbon Clean fuel stabilizer to prevent corrosion and keep your motor clean in the off-season. In addition, you'll want to fog your engine, which requires accessing your carbs or throttle bodies.
3. Remove & Store Your Battery
Removing your battery to keep it at a full charge and away from potentially corrosive debris can extend its life significantly. Choose a cool, dry location with an outlet nearby so you can attach your battery to a battery charger.
4. Remove Your Drive Belt
5. Inspect & Loosen Your Track
Tension on your snowmobile track and regular riding will wear it down over time. You'll want to inspect your track for wear at the end of the season, and reduce tension to give it a much needed rest for a few months.
6. Fix Broken Parts & Upgrade Your Accessories
Get ahead of next season by tuning up your sled, or adding an accessory you've had your eye on. There's no better time for maintenance and upgrades than when your snowmobile is already propped up and out of use for a few months.
7. Clean & Lubricate Your Snowmobile
Moisture, salt, dirt, and other debris can all find a way to corrode your snowmobile's most essential parts. While buffing up your sled looks cool, it's also a crucial step to ensure your machine's longevity. Every casing, bearing, chain and part deserves a solid clean and lubrication. Pick up some all-purpose cleaner, all-season grease, chaincase lubricant and go to town.
