I own a 2005 Sea Doo RXT. It's a 4-stroke supercharged 3-seater. It's the second ski I've owned. My previous was a yamaha gp1200 which was a two stroke.
I prefer the sea doo because it's a 4-stroke which makes for cleaner operation and easier fueling. Plus I can legally wakeboard behind it because it's a 3-seater.
The yamaha was faster but I couldn't tow a wakeboarder with it and it burned fuel extremely fast. It was also more difficult to handle. Also, it broke more than the sea doo.
BTW, they are all fun, fast and they all break alot. My yamaha actually sunk on me once.:eek:
