In theory they look very tempting. But you will have a lot more fun with a regular boat. When I used to own two Seadoo jetskis I followed the Seadoo boards quite regularly. Most people buy them and sell them the same year. You can probably get a used one almost anywhere. Yes, they use a lot of gas compared to even a boat with a 350 V-8! My Seadoo GSX used 13.5 gal/hr at full throttle, usually about 25 gallons a day. My brothers 25' V8 powered boat uses much less, typically 10 to 15 gallons a day.
