Transporting

When transporting your snowmobile on a trailer or in a
truck, observe the following recommendations to help
protect it from damage:

●

Make sure that the fuel level in the fuel tank is lower
than the bottom of the carburetors. Otherwise, the
vibration and bumps from the road surface could
make it possible for fuel to flow through the carbure-
tors into the cylinders. This can result in “hydrostatic
lock,” a condition where the engine cannot rotate
because of fuel accumulated in the engine. Severe
engine damage can result from hydrostatic lock.
When possible, the fuel tank should be empty during
transportation, especially if the trip takes longer than
30 minutes.

●

If transporting the snowmobile in an open trailer or
truck, put a tight fitting cover on the snowmobile. A
cover specifically designed for your snowmobile is
best. This will help keep foreign objects out of the
cooling vents in the shroud, and also help protect the
snowmobile against damage from debris on the road.

●

If transporting the snowmobile in an open trailer or
truck in areas where road salt is used, coat metal
suspension surfaces lightly with oil or another pro-
tectant. This will help protect against corrosion. Be
sure to clean the snowmobile when you get to your
destination to remove any corrosive salts.
