In only a few years, this trio of powerful 3.6-liter V6 outboards has changed all the rules and made two strokes ancient history. Suzuki's DF250, DF225 and DF200 outboards feature some of the most advanced engineering ever packed under a cowl — like digital sequential electronic fuel injection, dual overhead cams, a self-adjusting timing chain, variable valve timing (DF250), multi-stage induction for efficient airflow (DF250, DF225) and solid-state direct ignition.
