Yamaha F6 Portable Outboard Motor 2024 – 6HP Four Stroke

Yamaha F6 2024: Maximum Punch from Yamaha’s Smallest Portable Platform

The 2024 Yamaha F6 is the most powerful version of Yamaha’s 139cc single-cylinder OHV four stroke, producing 6HP at 5,500 rpm while weighing the same 59 lbs (15″ shaft) as its F4 sibling. That power-to-weight combination — plus refinement features like a labyrinth exhaust and long span mounting system for smooth, quiet operation — makes the F6 an impressive little outboard for real work. It runs a tiller handle with Forward-Neutral-Reverse shifting, 180° steering, and a balanced twist-grip throttle, and offers the convenience of an external fuel tank connection in addition to its built-in tank for extended range. In the small horsepower class, this is the top of Yamaha’s lightweight range before stepping to the bigger F8 platform.

Benefits

The F6 is the smart pick when you want maximum thrust without crossing into two-person-carry territory. It planes lightweight boats the F2.5 and F4 can’t, holds speed against wind and current, and the labyrinth exhaust keeps conversation-level noise even at working RPM. External tank capability turns it into an all-day fishing motor.

Applications

Perfect for 10–14 ft jon boats and aluminum skiffs, larger RIBs and tenders, duck boats, and sailboat auxiliary power (20″ shaft). Need electric start and more displacement? Step up to the Yamaha F8 2024. Watching budget and weight? The Yamaha F4 2024 shares this block at 4HP.
