I own a 2002 660 touring.
They are great ice fishing/touring machines. Especially with the quiet, efficient (20-25mpg), electric start, reverse, etc.. The engines will outlast the body, IMO.
However, if you are looking for speed this model is not for you. They max out around 50-60 mph. The turbo T660 models were introduced in 2004 models (and turbo is optional), and the performance is greatly improved.
They do have a block heater for the the really cold weather, and you may need it. 4 strokes don’t like the cold as much as the 2 strokes.
