📖 Model Background

The Yamaha F40B 4‑stroke outboard was introduced in 2007 and remained in production through around 2017, serving as Yamaha’s lightweight mid-power engine. It features a 747 cc three-cylinder SOHC EFI engine producing a reliable 40 HP, while weighing between 97–112 kg (214–247 lb)—making it one of the lightest four-stroke engines in its class. Its compact design includes a long-track intake manifold, single throttle valve, and electronic control module for smooth starts and responsive acceleration. With low exhaust noise, efficient fuel consumption, and options for tiller or mechanical remote steering, the F40B became a favorite for small pontoons, inflatables, and freshwater fishing boats.
