Although I've only had my 3D for a short time I have to say it’s the best thing that’s happened to riding in a long time. There is something to be said about the design of this watercraft. It rides great no matter what position you choose. I didn't opt for the cart seat although I probably will, based on other reviews. It's like 3 PWC's in one, ride as a stand up for a while and when you wear out from that, go to the moto position, what a great idea. The EFI addition to the proven 800 series Rotax engine is a nice feature for fuel economy and easy starting. I also like the low noise level and single cylinder idling. It’s also a very dry boat compared to previous PWC's I could go on and on...... Great job Sea Doo on this new exciting product! Be careful, if you ride one, you'll have to have one!
