Tohatsu MFS8 2025: The Light Twin
The 2025 Tohatsu MFS8 continues to combine two-cylinder refinement with class-leading light weight. Its 209cc (12.8 cu in) twin runs 8 HP (5.9 kW) across a 5,000–6,000 rpm range with a 2.08:1 gear ratio, full Forward-Neutral-Reverse gearing, manual or electric start, and shallow water drive. Less vibration through the tiller, quieter cruising, and an engine you can still lift onto the transom yourself — the appeal of the 8–10HP class done Tohatsu’s way.
