Yamaha F6 2025: 6HP of Smooth Four Stroke Power at Featherweight
The 2025 Yamaha F6 tops Yamaha’s lightweight portable range, extracting 6HP at 5,500 rpm from the proven 139cc single-cylinder OHV four stroke while holding dry weight to 59 lbs in the 15″ shaft version (20″ available). Refinements rare at this size — a labyrinth exhaust and long span mounting system — deliver notably smooth, quiet power, while the tiller handle provides Forward-Neutral-Reverse shifting, 180° steering, and a dampened twist-grip throttle. Its built-in fuel tank pairs with an external tank connection for extended range, and the decompression-assisted recoil starter with start-in-gear prevention keeps starting light and safe. For 2025, it remains the power pick of the small horsepower class.

Benefits
Fifty percent more power than the F4 at identical weight means the F6 planes boats its siblings can only push, punches through chop and current, and carries real loads — while staying light enough for one person to mount and stow. Quiet-focused engineering makes long days at the tiller genuinely pleasant.
Applications
10–14 ft jon boats and aluminum skiffs, larger RIBs and tenders, duck boats, and sailboat auxiliary duty (20″ shaft). Need electric-start convenience and bigger displacement? See the Yamaha F8 2025. Prioritizing economy? The Yamaha F4 2025 shares this block.
