📖 Model Background

The Yamaha 140 HP V4 2-Stroke outboard (1984–1996) is a compact high-performance engine designed for lightweight boats requiring strong midrange torque and efficient power delivery. Powered by a 1730cc (1.73L) 90° V4 engine with loop-charged induction and oil injection, this 2-stroke motor delivers reliable 140 HP with quick throttle response and smooth acceleration. Its smaller, lighter profile compared to V6 models makes it ideal for aluminum boats, bay boats, and mid-size fiberglass hulls.
