Yamaha LXF450USA Outboard Motor

30-Inch Shaft | 5.6-Liter V8 | Digital Electronic Control | EFI | Electric Start | Power Trim & Tilt | Gray | Counter Rotation

The Yamaha LXF450USA is built for boats that live offshore and take on serious water. This is the counter-rotation version of Yamaha’s most powerful outboard — the 450-horse V8. It’s designed to work alongside standard rotation engines, giving your rig smoother tracking, balanced thrust, and better handling when the seas turn rough.

Powered by Yamaha’s 5.6-liter V8, this motor delivers the kind of torque and top-end pull you can feel the moment you throttle up. The 30-inch shaft fits deeper transoms perfectly, giving large center consoles and sportfishing hulls the lift and control they need offshore. And like every Yamaha V8, it’s built to run hard, last long, and stay dependable no matter how tough the conditions get.

⚠️ Installation Notice

This engine uses Yamaha’s Digital Electronic Control (DEC) system. It must be installed by an authorized Yamaha dealer. Both the outboard and controls require Yamaha software setup during installation. DIY installation is not supported.

Q: What’s the main difference between the LXF450USA and XF450USA?

A: They’re the same engine—same power, same shaft—but the LXF spins in the opposite direction for use in counter-rotating setups.

Q: What type of boats use this motor?

A: It’s built for large offshore boats, center consoles, and multi-engine rigs where control, balance, and reliability matter most.
