Yamaha LXF450USA Outboard Motor

30-Inch Shaft | 5.6-Liter V8 | Digital Electronic Control | Electronic Fuel Injection | Electric Start | Power Trim and Tilt | Gray | Counter Rotation

The Yamaha LXF450USA is the counter-rotation version of Yamaha’s most powerful offshore outboard, designed for multi-engine rigs that demand balance, stability, and control. Powered by the 5.6-liter V8 platform, this 450-horsepower outboard delivers relentless torque and top-end speed while maintaining Yamaha’s legendary reliability. Its 30-inch shaft is ideal for deeper transoms on large offshore hulls. When paired with standard rotation models, the LXF450USA reduces steering torque and provides balanced thrust for superior handling in offshore conditions.

⚠️ Important: This is a Digital Electronic Control engine and must be installed by an authorized Yamaha dealer. Both the outboard and the Digital Electronic Control system require flashing and configuration with Yamaha diagnostic tools during installation. DIY installation is not supported.
