As for the Can Am itself, I have never ridden one. However, as an owner of multiple Ski Doo snowmobiles, and friends with those who have owned multiple Ski Doo snowmobiles and Sea Doo watercraft, I can say that Rotax engines are very reliable. I have a 600 ACE in one sled, and a 900 in another. I ran the 600 WOT across an 8 mile long frozen reservoir (7200 rpm) and it took it in stride, no oil consumption. Rotax is not in the same league as a 4-stroke engine builder as Honda, Yamaha, Suzuki, however. Their engines need more cc's to generate equivalent power, throttle response is not as sharp, and exhaust tone leaves something to be desired.

Ski Doo build quality is a notch below the Yamaha snowmobiles I used to own (prior to their sleds being manufactured by Arctic Cat).
