Improved Durability
A proven 498cc two-cylinder, SOHC design
features a new cylinder block and head.
The pistons, connecting rods, and valves are
the same as used in its F60 big brother, for
added strength, responsive power and excellent
fuel effi ciency in a compact package.
Greater Reliability
Turn-Key Starting
: Air
: Fuel
: Mixture
Yamaha’s PrimeStart™ system is standard on
F25 and T25 models, for dependable turn-key
starting in either hot and cold conditions.
Responsive, Fuel-Effi cient Power
POWERFUL PERFORMANCE
New electronics and a new micro-computer
controlled ignition system mean dependable
starting and consistent power, while an advanced
air intake system drains away any water that
enters the cowling during normal engine operation
for long-term reliability.
Smooth and Quiet
: Exhaust
Engine exhaust is routed through a maze before
exiting above the waterline through the idle
exhaust relief outlet for unbelievably smooth
and quiet operation.
A streamlined intake manifold uses long
tracks and smoother airfl ow, for reliable
and responsive power with outstanding
fuel effi ciency.
Choice of Controls
Multi-Function Tiller Handle
(Optional: F25 remote models)
Tiller handle models feature improvements in
strength and operator comfort, with stronger
internal components and an improved grip.
Our Multi-Function Tiller Handle is also available
