Here’s what you’ll need:

  • One gallon of ethanol
  • free premium gas
  • Fuel stabilizer
  • A fuel pump or siphon
  • Basic car washing supplies
  • A grease gun and all-purpose grease
  • A shop rag-And 3-4 2×4 blocks cut to 18”

Here are the steps:

  • First, lubricate the rear suspension at the three Zerk fittings.
  • Next, siphon out any fuel older than about 60 days. Or, if your fuel isn’t that old, you can burn the fuel by running the engine until the fuel gauge reads one bar. But don’t run it totally dry. Add fuel stabilizer to a gallon of fresh non-ethanol gas. Then add the mixed fuel back into the snowmobile tank. If you don’t have ethanol-free gas near you, just use premium.

  •  Next, we’re going to fog the engine using the following steps:

-Place your sled outside, or in a well-ventilated area.

-Start the engine and let it run at idle until the coolant temperature warms up to about 3 or 4 bars on the display.

-Cycle through the modes, stopping at the odometer.

-While holding down the mode button, rapidly toggle the headlamp switch from High to Low beam until the gauge displays “Press/Hold Button For Oil Injection.”

-Release, then press and hold the mode button one more time for 3 seconds.

-When the gauge reads “Oil,” release the mode button and wait for the engine fogging to complete. This takes about 15 seconds, during which the engine will rev up to about 1600 RPM. Let the process complete interruption-free. At the end of the process, the engine will automatically shut off. Once you’re done fogging the engine, it’s recommended not to run it again until next winter.

  • Once your engine is fogged, wash your sled with mild soap and water to prevent corrosion from salt deposits.
  • Wheel or lift your sled into its summer storage location. Once it’s in place, we want to raise the track off the ground to keep the paddles from forming to the surface below. I’m using 2×4 blocks cut to 18 inches. Use blocks, rollers or a snowmobile lift to keep the rubber track off the ground.

  • Now cap the muffler opening to keep debris and rodents out.
  • Store your sled in a shaded and cool environment. Or, if you must store it outside make sure to use a quality cover that is well secured.
