📖 Model Background

The Yamaha 50 HP 2-cylinder 2-stroke outboard, manufactured between 1997 and 2003, was a rugged, lightweight engine designed for reliable performance in small to mid-sized boats. Using a 698 cc loop-charged inline-2 engine with oil-injection and CDI ignition, it delivered consistent 50 HP output with minimal maintenance requirements. Weighing around 87–92 kg (192–203 lb), this engine was commonly paired with jon boats, inflatables, utility craft, and tiller-steered fishing rigs across freshwater and coastal markets.

This manual covers all Yamaha 50 HP 2-stroke 2-cylinder models from this range, including variants such as 50TLR, 50D, 50BETOX, and other configurations based on the same 698 cc engine block. All ignition, fuel, cooling, trim/tilt, and control systems are thoroughly included in the service procedures.
