📖 Model Background

The Yamaha 140B two‑stroke outboard, launched in the late 1980s, was part of Yamaha’s high‑power V4 series (similar to the S130X). With a displacement around 1.4 L and an inline‑4 loop‑charged engine, it delivered a stout 140 HP in a compact package. Popular in export markets, the 140B featured a solid build with durable V4 heads, oil-injection capability, and efficient coolant and exhaust systems. Despite the lack of detailed publicly available specs, parts catalogs confirm its rugged design and continued parts support, suggesting it was a reliable performer for its time.
