Don't know about SeaDoo models, but you might want to check out a couple of Yamaha GP800R skis. Pretty fast and fun, and I see some good prices on them. For any 10 year + 2 stroke, I'd look at converting them to premix if not already converted. I think some of the GP800s had powervalves, so I'd also check for that, to see if they had already been fixed. Otherwise, a very nice reliable ski.
