I run a sport sled for ice fishing. It isn’t really all that ideal since the machine wants to run at WOT (wide open throttle) at all times. Mine is a 136″, however. 2006 Ski-doo Renegade 800X. I also have trouble, like Munchy said, with overheating without plenty of snowcover on the lake. If your goal is to get to the fishing spot at 85MPH, it’s great…If your goal is to get there without breaking gear, a different sled would be ideal. For me, I get by with what I have and it works alright. Just be prepared to deal with heat issues and feathering the throttle.
