📖 Model Background

The Yamaha XF375, part of the XTO Offshore lineup, was introduced in 2018 as a high-horsepower 4-stroke outboard designed for serious offshore performance. Sharing the same 5.6-liter V8 architecture as the XF425, the XF375 delivers 375 HP with exceptional torque, direct fuel injection, and Yamaha’s industry-first integrated electric steering system. Built for large offshore boats and sportfishing vessels, the XF375 combines cutting-edge technology with the rugged durability Yamaha is known for. Key features include digital electronic controls (DEC), compatibility with Helm Master® EX joystick system, and a robust gearcase designed for heavy-duty offshore loads. The 2018–2020 XF375 offers smooth power delivery, precise control, and long-distance reliability for demanding marine environments.
