The Yamaha Outboard – LF300USB is a premium offshore counter-rotating outboard built for stability, precision handling, and dependable power in challenging marine environments. Powered by Yamaha’s advanced 4.2-liter V6 with Variable Camshaft Timing (VCT) and Electronic Fuel Injection (EFI), it delivers strong acceleration, smooth midrange performance, and excellent fuel economy.

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