2016 Yamaha Boats SX 240 HO 2016 YAMAHA SX 240 HO, One owner Yamaha Jet Boat with a trailer included. Look at this lightly used boat before taking the depreciation on a new one.When it comes to the Yamaha SX240 one of the first words that pops to our mind is performance. During tests of the SX240 HO, this boat felt light, nimble, and exciting, with plenty of power. Yamaha delivered with nothing but the highest quality materials, level of execution, performance numbers, and low speed handling and maneuverability. Let's just say that a large amount of thought and time went into the power to push this bowrider across the water at 45 mph plus.
