Excitement Awaits The 23 SSi outboard combines everything great about the 23 SSi with the power, performance, and quality of a Yamaha Outboard. Coupled together, this makes a combination that's hard to beat. Saltwater or Freshwater, this outboard-powered 23-footer is guaranteed to impress. Quick to plane, full of power, and full of all the standard features that set Chaparral apart from the rest.
