I am new to Waverunners and I have the chance to buy a 1998 Seadoo GTS Bombardier Jet Ski 3-Seater (2-stroke) with a solid trailer. The cost is $2000. I am concerned about whether or not 2 strokes will be around anymore because I heard pollution laws are coming into effect that may hurt the 2-stroke. Also I am going to look at the Waverunner tomorrow and would like to get some advice on what I should be looking for internally in order to know that this is a solid buy. Lastly I am wondering if anyone can tell me the amount of gas a 2-stroke seadoo expends? It is a 7 gallon tank, at least that's what he said. He told me he takes it to the lake all day and still has gas left in the tank when he's done but I also heard wavreunners can expend gas up to 10 gallons an hour.
