I just bought a Expedition 900 Turbo swt and love it went from a Expedition 20-in wide with a 600 E-Tec the 600 seemed a little bit snappier but the 900 has all kinds of Power. The 900 has the Eco Mode and if you put it in that it seems like it would crawl out of anything or if you want to put it in sport mode it takes right off. And so far I am loving the 4-stroke I did get the block heater on it and have plugged it into the generator for approximately a half an hour before I ride gets the engine oil temp up so starting has been easy.
