📖 Model Background

The Yamaha F375 (2018–2020) is the standard-rotation version of Yamaha’s 5.6L XTO Offshore outboard lineup, offering the same advanced engineering and performance as the XF375 but tailored for single-engine or starboard-side multi-engine setups. Powered by a 5.6-liter V8 DOHC 4-stroke engine with direct fuel injection, the F375 delivers 375 horsepower with exceptional mid-range torque, clean throttle response, and outstanding fuel efficiency. Like its higher-horsepower sibling, the F425, the F375 features integrated electric steering, digital electronic controls (DEC), and is fully compatible with Yamaha’s Helm Master® EX joystick control system. Ideal for large center consoles, sportfishing boats, and offshore cruisers, the F375 delivers premium performance with Yamaha’s proven reliability.
