Our 432-cc 25-hp portable outboard sports a new, streamlined,
portable design and class-leading power-to-weight. In fact, its the
lightest 25-hp outboard on the water—two-stroke or four-stroke.
While its streamlined design is 25 percent lighter, 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.
Variable Trolling RPM Switch (VTS®) is standard when equipped
with new factory-equipped tiller handle or optional Multi-Function
Tiller Handle, a Command Link® tachometer or dash mounted VTS
switch
Alternator Output at W.O.T. 16 amp
Recommended Fuel Filtration Yamaha 10-Micron Fuel/Water
Separating Filter (external)
C.A.R.B. Rating 2-Star
A 45-degree steering angle in each direction means great
maneuvering potential.
A Freshwater Flush Device allows you to flush the engine
without running it, for added convenience and extended engine
life.
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.
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.
The F25, F20 and F15 all feature a two-valve-per-cylinder,
single-overhead-camshaft design that provides better breathing and
more power.
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
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.
Yamahas F25 has gone through a redesign so transformative, its
now the lightest 25-horsepower outboard on the water—two stroke or
four stroke. Its new portable design and class-leading
power-to-weight mean 25 horses can boldly go where theyve never
gone before. Jons. 14-foot aluminum fishing boats. The bed of your
truck.
