However, it’s not recommended to start your snowmobile during the summer, and understanding how snowmobile engines work is crucial to comprehend why.

Understanding Snowmobile Engines

Snowmobiles, like any other engine, operate by combustion. Initially, the engine generates power, which is then transferred to the transmission, commonly known as CVT. Subsequently, the CVT conveys the power to the drive train system.

Running the engine generates a substantial amount of heat. To manage this, snowmobiles are equipped with a heating system responsible for temperature regulation. This system operates dually, utilizing a cooling liquid such as coolant. Additionally, snow plays a vital role in this process.

As the sled tracks rotate, they come into contact with the heating system. This interaction ensures that the snowmobile maintains the correct temperatures for optimal performance.

Summer Conditions Vs Winter Conditions

Understanding the distinctions between summer and winter conditions is straightforward. One significant factor is the absence of snow during the summertime. Let’s delve into the primary differences between winter and summer conditions:

Humidity Levels

During summer, winds carry more humidity compared to winter winds. In winter, water molecules combine to form snow, contributing to the perception of winter winds as crisp and dry.

Despite snow getting into the tracks of your snowmobile during winter rides, it doesn’t negatively impact the sled. The low temperatures play a crucial role in preventing any adverse effects.

What To Do With A Snowmobile During Summertime?

While starting your snowmobile during the summer is not recommended, there are alternative activities you can engage in:

Water Skipping

Some enthusiasts practice water skipping, taking their sleds on water similar to a jet ski. However, sleds don’t float like jet skis. Although you can move across a lake or river at a constant speed, there’s a risk of drowning if water enters the exhaust and damages the engine.

Drawbacks of Water Skipping

The primary drawback is that sleds lack buoyancy, increasing the risk of sinking. If water reaches the engine through the exhaust, it can lead to significant damage.


“Summerizing” is the process of preparing your snowmobile for storage during the summer months. Here’s how to do it:

  1. Pour a fuel stabilizer into your sled tank to prevent corrosion and damage to the engine.
  2. Turn on the engine after adding the stabilizer.
  3. Once you observe white fog coming out of the exhaust, turn off the engine.

Additional steps for “summerizing” involve:

  • Removing the battery.
  • Applying grease to the sled.
  • Removing weight from the rear to protect the suspension system.

These steps help ensure your snowmobile is adequately prepared for storage during the summer, preserving its condition and performance.

Frequently Asked Questions (FAQs)

Should you start your snowmobile in the summer?

No, starting your snowmobile in the summer is not recommended. “Summerizing” is a more effective and less risky way to prepare it for storage.

Is it bad to run snowmobiles on grass?

Yes, it is not ideal. Snowmobile tracks are designed for snow, which is softer than grass. Running on grass can lead to overheating.

Can you run a snowmobile without a battery?

Yes, manual snowmobiles start without batteries, while others can be jumpstarted.

Can you use a snowmobile on sand?

Yes, but running on sand can transmit heat to the sled’s heating system.

How do you start a snowmobile that has been sitting?

Check spark plugs, carburetor, and fuel tank. Add starting fluid with lubricant if needed.

How do you start a badly flooded snowmobile?

Let it sit for a few hours, remove spark plugs to dry, or seek professional assistance.

Is it ok to store a snowmobile outside?

Yes, it’s okay, but precautions like plugging the exhaust, placing it away from trees, and using a cover can protect it.

What temperature is too hot for a snowmobile?

Snowmobile temperature should be between 104°F and 170°F, depending on the type.

What happens when you overheat a snowmobile?

The sled alerts you, shuts down the engine, and requires cooling before restarting.

What causes a snowmobile to overheat?

Issues with engine oil, cooling liquid levels, and fuel quality can cause overheating.

Can you put a radiator on a snowmobile?

Yes, some models come with radiators to prevent overheating.


Running a snowmobile in the summer offers various recreational possibilities, such as engaging in drag racing, water skipping, or navigating through sandy terrains. However, each activity carries its own set of risks.

Activities like drag racing and sand traversal can subject your engine to significant stress, potentially leading to overheating issues. Moreover, the sled’s heating system may struggle to cope with high temperatures.

Alternatively, water skipping might not pose a risk of overheating, but it brings the potential hazard of the sled sinking or water entering the engine.

If you want to play it safe, summerizing your equipment is the best option there is. However, if you feel like there’s more you can do with your sled, a good insurance policy could be a wise move to protect your investment.
