The Yamaha Outboard – LF300ECB2 delivers maximum offshore capability with precise handling and deep-water performance for vessels requiring extended propeller depth. Its counter-rotation system reduces steering torque in twin or triple installations, while the 35-inch shaft ensures propeller immersion in demanding seas.
Built on Yamaha’s proven 4.2-liter V6 platform with Variable Camshaft Timing (VCT) and Electronic Fuel Injection (EFI), it provides exceptional acceleration, fuel efficiency, and smooth throttle response. The Pearl White finish offers a premium look while providing superior corrosion resistance for saltwater use.
⚠️ 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.
