There are many professional snowmobilers, and hundreds of teams, I will talk about the Skidoo X-Team. The X-Team is a snowmobile racing team. One of their racers, Korbyn Anderson, number 17 grew up in Detroit Michigan and has become one of the largest snowmobile racers in the world. His main sponsors are MBRP and Skidoo, he uses a Skidoo XPS in his races and is a top tier racer.

Connor is another X-Team racer. His racing number is 816 and he is also a top tier racer. He races is the Sno-Cross races. Connor races with a Skidoo MXZ RS snowmobile, and is sponsored by Beissel Farms, Hayward Powersports, Ski-Doo, Great Lakes Hybrids, and his own father! That would be a dream to be sponsored by your own father.
