For those who want more, the answer is here. Featuring the same 5.6-litre big-block displacement and long list of features as the XF425, the all-new XF450 improves upon the powerful platform that changed the offshore boating game. With more charging, convenience, functionality and horsepower, the Yamaha XF450 will make a splash.


  • Even more charging power: Using Phase Angle Control (PAC), which adjusts the intensity of the stator’s magnetic field, XTO Offshore 450 models produce up to 96 net amps per engine in neutral. The new XTO Offshore provides more power for today’s popular on-board, high-demand devices like gyro stabilizers, air conditioning, sound systems, and more, all while keeping starting batteries constantly charged.
  • Highest compression ratio in an outboard: Get more “bang” from every spark with a 12.2:1 compression ratio: better efficiency, more power and incredible throttle response. 
  • Plasma-fused sleeveless cylinders: This micro-textured surface is 60 percent harder than steel, yet significantly lighter and thinner, increasing displacement without increasing the size of the powerhead. Other benefits include reduced friction, faster heat transfer and improved fuel economy.
