📖 Model Background

The Yamaha DX150X 2‑stroke outboard, produced from 1998 to 2005, was part of Yamaha’s performance “DX/SX” inline‑5 150 HP series. Featuring a 1.7 L loop‑charged engine with three dual‑throat carburetors, CDI ignition, and oil-injection, it delivered strong mid‑range torque and reliable power. Weighing about 187 kg (411 lb), the DX150X stood out for its robust build and fuel efficiency. Many owners praised its “strong midrange and surprisingly good fuel economy” despite being a carbureted engine.
