Last year, Yamaha came out with the SX190, a 19-foot jet boat that uses a single 1.8L jet-drive engine rather than the twin engine setup of its 21- and 24-foot models, giving prospective sportboat owners a more affordable package. This year, the designers have upped the ante with the SX192, which features the extra 30 hp kick of a supercharged 1.8L SHO engine.
