📖 Model Background

The Yamaha 30D 2‑stroke outboard was produced from around 1998 to 2003, part of Yamaha’s compact 30 HP mid-range series.

Featuring Yamaha’s “Precision Blend” oil-injection, it offers adjustable fuel/oil ratios from about 200:1 (trolling) to 80–50:1 (wide-open throttle), improving efficiency and performance. Weighing approximately 58 kg (128 lb) and available in manual or electric start and tiller steering, the 30D is praised for balanced portability, reliable power, and clean-running operation.
