Yamaha LXF450ESA4 Outboard Motor

35-Inch Shaft | 5.6-Liter V8 | Digital Electronic Control | EFI | Electric Start | Power Trim & Tilt | Classic White | Counter Rotation

The Yamaha LXF450ESA4 is the 35-inch-shaft, Classic White counter-rotation version of Yamaha’s most powerful offshore outboard. Under its clean, premium finish sits a 5.6-liter V8 delivering a true 450 horsepower—built for heavy offshore hulls that demand strength, balance, and confidence at sea. In multi-engine setups, its counter-rotation gearcase evens out prop torque, giving you steadier tracking and lighter steering in rough water.

This model is tuned for serious offshore performance yet designed with luxury rigs in mind—perfect for deep-V center consoles, large fishing boats, and yachts that need both muscle and style.

⚠️ Important Installation Note

This outboard uses Yamaha’s Digital Electronic Control (DEC) system and must be installed by an authorized Yamaha dealer. Both the engine and control system require flashing and calibration with Yamaha diagnostic tools. DIY installation is not supported.
