1) Light - Can be unstuck from slush and drifts easily without the use of another snowmobile. Furthermore, the less weight on the early ice the better. Primarily this leads to the use of a two cycle engine.
2) Reliability - It would be really nice (and perhaps not realistic) to have a snowmobile that is as reliable as a car. Getting stuck in winter weather is really bad in a car. On a snowmobile miles from anyone else is much worse.
3) Strong - it would be best to have the option of towing other snowmobiles and equipment on and off the ice without providing strain beyond which the snowmobile is designed.
4) Suitable track - I have heard that there are trade offs between the smoothness of the ride and the ability to the snowmobile to traverse drifts and slush. I could use some input on this subject.
5) Temperature versatility - I have heard that some snowmobiles do better than others depending on what the temperature is.
6) Longer track - A longer track would distribute weight better as well as allow for a longer seat for an additional passenger.
So, does anyone know if there is such a snowmobile? Or if there are any other criterion upon which this choice could be based? I have actually seen a variety of different vehicles (4 wheelers as well as fan boats ect.) on the ice. Can anyone tell me why one would choose such vehicles?
