PORTABLES

Mechanical or Tiller: 25 hp, 20 hp | Tiller: 15 hp

The marsh rustles in the fall breeze as you deploy your decoys. There’s nothing like a trusty Yamaha Portable outboard for a crisp day of fishing or duck hunting. Yamaha’s Portable F25, F20 and F15 pack impressive power-to-weights and all the advantages of Yamaha’s award-winning, portable design, including carrying handles, incredibly light weights and more. The F25 even comes in matte brown, in case stealthy is part of the ask. No matter what’s ahead, your Yamaha Portable will be ready to go.

Meet the Lineup

25 HP

Our 432-cc 25-hp portable outboard features a streamlined, portable design and class-leading power-to-weight. While it’s 25 percent lighter than its previous design, it still packs exciting features like battery-less EFI. Pull-start models can now take advantage of this feature, plus the system is designed with an automatic decompression device to require even less effort for manual starting.

  • Now available in new pearlescent white and matte brown*, in addition to Yamaha gray
  • Only 126 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths and in a High-Thrust design (T25)
  • Powerful 16-amp alternator
  • Variable Trolling RPM Switch (VTS®) accessible depending on rigging
  • Select models, including 15-inch shafts, feature a shorter tiller with Power Trim & Tilt and a tilt-up feature for ease in small spaces

*New color options available in select models and subject to availability.

20 HP

Our 362-cc 20-hp portable outboard is built on the same award-winning platform as the F25. Its SOHC in-line design and streamlined intake manifold delivers solid power. Not only that, but it’s one of the most fuel efficient in its class. At just 126 pounds, it’s suitable for lightweight craft such as aluminum fishing boats, tenders and inflatables.

THE OUTSTANDING,

25 HP PORTABLE

Yamaha’s F25 is still the lightest 25-horsepower outboard on the water—two stroke or four stroke. Its portable design and class-leading power-to-weight mean 25 horses can boldly go where they’ve never gone before. Jons. 14-foot aluminum fishing boats. The bed of your truck.

Features & Benefits

Efficient Power

The F25, F20 and F15 all feature a two-valve-per-cylinder, single-overhead-camshaft design that provides better breathing and more power.

Optimum Performance

An optimally balanced crankshaft and labyrinth exhaust deliver smooth power, while Microcomputer Ignition adjusts timing to maintain maximum engine performance, economy and power under all conditions.

Streamlined Intake

An intake silencer and manifold on the F20 and F15 result in more direct airflow, for minimum noise and maximum power. 

Responsive Acceleration

An acceleration pump on the F20 and F15 gives the engine the fuel it needs--when it needs it--like during rapid throttle advance. This ensures responsive acceleration

MAX MANEUVERABILITY

A 45-degree steering angle in each direction means great maneuvering potential.

EASY ENGINE FLUSHING

A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.

PORTABILITY AND STORAGE

Incredible light weights, built-in resting pads and carry handles, an easy oil retention system and an optional folding tiller handle, allow for easy carrying and on-side storage without oil leakage or cowling scuffs.

RELIABILITY & DURABILITY

OPTIMAL OPERATION

CDI Microcomputer Ignition monitors throttle position, engine speed and atmospheric conditions in order to precisely adjust ignition timing under all conditions for optimum ignition performance, ensuring smooth and reliable operation.
