#Year-2022|Model-F25swtc
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.
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:
- Color - Gray
- Only 126 pounds
- Shaft Length - 15"
- 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
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.
Engine Warning System
Protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, start-in-gear protection and shift-in prevention at open throttle.
Wet Sump
A pressurized oil delivery system incorporates a compact and durable oil pump to keep all of the moving parts of their SOHC systems lubricated and running smoothly for maximum reliability.
Corrosion Protection
Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Portable outboards.
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 Fllushing
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.

#Year-2023|Model-F25swthc2
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.
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:
- Color - Pearlescent White
- Only 126 pounds (15” shaft model)
- Shaft Length - 15"
- 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
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.
Engine Warning System
Protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, start-in-gear protection and shift-in prevention at open throttle.
Wet Sump
A pressurized oil delivery system incorporates a compact and durable oil pump to keep all of the moving parts of their SOHC systems lubricated and running smoothly for maximum reliability.
Corrosion Protection
Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Portable outboards.
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.

#Year-2023|Model-F25lwhc
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.
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:
- Color - Gray
- Shaft Length - 20"
- 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
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.
Engine Warning System
Protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, start-in-gear protection and shift-in prevention at open throttle.
Wet Sump
A pressurized oil delivery system incorporates a compact and durable oil pump to keep all of the moving parts of their SOHC systems lubricated and running smoothly for maximum reliability.
Corrosion Protection
Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Portable outboards.
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 Fllushing
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.
