Tohatsu MFS9.8 2025: The Sailor’s Favorite
The 2025 Tohatsu MFS9.8 continues as one of the most sought-after small outboards on the water. The 209cc (12.8 cu in) twin produces 9.8 HP (7.2 kW) at 5,000–6,000 rpm through 2.08:1 Forward-Neutral-Reverse gearing, and Tohatsu keeps it among the lightest engines in its class — the reason it dominates sailboat sterns and kicker brackets. Manual or electric start, shallow water drive, and the Sail Pro variant with extra-long shaft and high-thrust propeller make it endlessly adaptable in the 9.9HP outboard class.
