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.

Greater Reliability

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.

Responsive, Fuel-Effi cient Power 

A streamlined intake manifold uses long 
tracks and smoother airfl ow, for reliable 
and responsive power with outstanding 
fuel effi ciency.

Turn-Key Starting

Yamaha’s PrimeStart™ system is standard on 
F25 and T25 models, for dependable turn-key 
starting in either hot and cold conditions.

Choice of Controls

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 
on remote control F25 models.

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.
