Yamaha has finally given the world an all-new Superjet stand-up personal watercraft and it rips! After 30 years of creating my favorite two-stroke stand-up, Yamaha created a clean-sheet design boat powered by the epic three-cylinder, 100hp TR1 four-stroke engine. The new ride does everything well and in this video I weigh it and every other generation of Superjet to see how heavy each one is and then I go wide open throttle to see how fast they are.
