These are the benefi ts Yamaha constantly strives to provide in every outboard we make. Continuing 
this innovative tradition Yamaha is proud to announce the newest additions to our mid-range outboard 
family, the four stroke F25 and four stroke, high thrust T25.

 

PERFORMANCE

 

 Our 

marine-specifi c, two-cylinder, single overhead camshaft design features a new cylinder 

 

block and head for enhanced durability and economical power in a compact package.  

 

A new streamlined cowling coupled with a tuned long intake track manifold and 

 

our PrimeStart™ system mean outstanding fuel-effi ciency with easy starting, fast 

 

acceleration, and excellent top-end speed.  Available in both standard and 

 high-thrust 

models.

 

RELIABILITY

 

 

Yamaha’s proven design features advanced technology like 

 

new electrical components and a new micro-computer controlled 

 

ignition system.  In addition, new pistons, connecting rods, and valves mean 

 

greater strength for added reliability. Add a spin-on oil fi lter, integral engine 

 

monitoring and warning system and Yamaha’s renowned Ultimate Corrosion 

 

Protection System, and you have the features to help provide the peace 

 

of mind that comes standard with every Yamaha outboard. 

 

CONVENIENCE AND CONTROL

 

 

Yamaha’s F25 and high-thrust T25 offer the ultimate in convenience and control 

 

in a wide range of applications; all in a compact, easy-to-own-and-operate package.  

 

All models feature our Long Span Mounting System, helping to reduce vibration for 

 

smoother operation. Standard tiller handle models have an improved handle featuring 

 

greater strength and improved comfort.  The high-thrust version T25 features a standard 

 

Dual Thrust™ propeller, a larger lower unit with a high 2.42:1 gear ratio, electric start, 

 

power trim and tilt, and remote control; making it ideal power for heavy loads like 

 

small pontoons, sailboats, and work boats.

 

VALUE

 

 

Yamaha reliability. Exceptionally smooth and quiet operation. Outstanding fuel effi ciency. 

 

Maximum performance and convenience. A 3-year pleasure use limited warranty, with a new 

 

CARB 3-star rating.  Yamaha’s new F25 and T25 are incredibly powerful and versatile values.
