I have a 2001 S22 with about the same hours on it. I am the original owner and have had zero problems. Make sure that it has been maintained, as in yearly fluid and filters changes and that the impeller has been changed at least a few times. It is a great boat and easy to work on, thanks to this forum and the guys on it. I change my oil in the engine, trans, and vdrive at the end of every season. I also change my water/fuel separator filter along with my oil filter at the same time. I change my impeller every other year. I do it all myself and it is very easy.
Good Luck
Dennis
