Yamaha LF250ECB Outboard Motor

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

The Yamaha LF250ECB is a counter-rotation offshore workhorse, purpose-built for tall-transom vessels that require maximum control, balanced handling, and long-term reliability. Powered by Yamaha’s renowned 4.2L V6 four-stroke platform, this 250-horsepower engine delivers outstanding midrange torque, smooth acceleration, and excellent fuel economy—making it a top choice for offshore fishing boats, multi-engine cruisers, and bluewater adventures.

The counter-rotation propeller system pairs perfectly with a standard-rotation F250ECB to improve tracking, reduce steering effort, and enhance stability in challenging sea conditions. With Digital Electronic Control (DEC), throttle and shift response are precise, smooth, and effortless. The 35-inch shaft length ensures proper propeller depth for deep-transom designs, maximizing performance and efficiency offshore.
