No sane person would even think about it. What if the engine shuts down due to some reason? What if the snowmobile topples? IT STRAIGHT AWAY SINKS. Thats why nobody would try this. But a group called StuntFreaksTeam have performed that and made it look absolutely easy. Just go fast enough n start performing Wheelies. Done. That easy. Polaris switchback assault 800 which has an 170 HP moter was the vehicle used in this stunt.
Enjoy it and try it if you want. But on your own snowmobile!!
