Solutions
• Drive at higher RPMs. Gear the machine down. Check
belt deflection.
• Warm the engine at least five minutes. Take the drive
belt off the snowmobile in extremely cold weather and
warm it up. Break snowmobile loose from the snow.
• Do not tow in deep snow. Use fast, aggressive throttle
to engage clutch.
• Lower the gear ratio. Reduce RPM. Avoid riding in
high ambient temperatures. Check for snow ingestion.
• Warm the engine at least five minutes. Take the drive
belt off the snowmobile in extremely cold weather and
warm it up. Break snowmobile loose from the snow.
• Check for fouled plugs and water, ice or dirt in the fuel
tank or fuel line.
• Skis may gouge into trailers and prevent the drivetrain
from spinning properly. Use enough speed to drive the
snowmobile completely onto the trailer. Push and pull
it to finish loading if necessary.
• Inspect clutch components. See your dealer.
• Use fast, aggressive throttle to engage clutch.
