📖 Model Background

The Yamaha 90 HP 3-Cylinder 2-Stroke outboard (1984–1996) is a lightweight, high-revving engine known for its simplicity, power-to-weight ratio, and long-standing reliability. Powered by a 1140cc (1.14L) inline 3-cylinder, loop-charged engine with oil injection, the 90 HP model delivers brisk acceleration and smooth performance — ideal for lightweight fiberglass boats, aluminum fishing rigs, and flats boats. Its durable mechanical design, combined with CDI ignition and carbureted fueling, made it a go-to choice for boaters seeking minimal maintenance and maximum value.
