For 2016, Yamaha is introducing an all-new marine motor to be featured in its V1 Series and VX Series WaveRunners (excluding VX Cruiser HO). The Yamaha TR-1 HO marine engine is the pinnacle of engine innovation. The TR-1 motor is 13 percent more powerful than the Yamaha MR-1 engine that it is replacing while being 40 percent smaller in size and 20 percent lighter in weight. Yamaha achieves this by eliminating a reduction gear, integrating the oil tank, and using fewer and smaller parts. The result is quicker acceleration, higher top end speeds, with better fuel economy and more fun for the rider. It is the fourth engine that Yamaha builds for Marine use after the MR-1, the 1.8 liter engine (in NA and SC editions) and the four-cylinder NA engine which was used until now in the VX series.
