That's not an I/O... that's a direct drive.
If you are hard core into wake boarding, then that's the boat to have. I love my little SeaDoo boat, but I'll be the first to admit, that none of the SeaDoo boats do a great job for wake boarders.
I think next summer, I'll be selling the Sportster, and buy an Islandia. Probably on 06 or 07 with twin Rotax, and no superchargers.
