These are large and carry three people but handle very well and it will do 66-68 on the speedo with 1/4 tank of gas. The watercraft is powered by a four stroke yamaha engine 160 factory horsepower, but like i said i did put the riva kit on it which includes, exhaust, air filter, and velocity stacks for power gains. For handeling the riva kit includes a new impeller, ride plate, intake grate, pump seal kit, and pro series sponsons. This waverunner will turn and dig at 55 mph. Very easy to outrun the smaller faster jetskis as long as they dont have perfect water.
