I live in Alaska and we are looking at buying a 2008 Seadoo 150 Speedster with the 215hp engine. I know your thinking Alaska? .....but we run our jetskis year around just put on a drysuit, take a radio and epirb and we are on our way...always in pairs. I have never owned a Speedster and want your thoughts on durability and engine issues. We flush our bikes with fresh water each time we come back and I like the fact that the Speedsters have an enclosed coolant system.....thanks for any information!....mike
