A couple of points on the Ski Nautiques. They had the Euro slant back until 1996 (the NWZ hull). The new and improved hull with the bubble back (TSC) began in 1997 and continued through 2001. 2002--2005 (TSC2). 2006--2009 (TSC3). All good hulls. Also, all Ski Nautiques in the range you mentioned had gear reduced (1.23:1) transmissions standard.
Good luck with your search.
