Yamaha LF250XSB Outboard Motor

25-Inch Shaft | Counter Rotation | DEC (Digital Electronic Control) | Electric Start | Power Trim & Tilt | Gray

The Yamaha LF250XSB is a premium counter-rotation outboard designed for twin-engine offshore setups where balance, control, and durability matter most. Built on Yamaha’s proven 4.2L V6 four-stroke platform, it delivers 250 horsepower with strong midrange torque, excellent acceleration, and outstanding fuel efficiency.

⚠️ 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.

With Digital Electronic Control (DEC), the LF250XSB offers smooth, precise throttle and shift operation for confident handling in any condition. The counter-rotation design improves tracking and reduces steering effort when paired with a standard-rotation F250XSB, making it ideal for deep-V hulls, offshore fishing vessels, and multi-engine sport boats.
