F2.5

The smallest model in Yamaha’s four-stroke lineup, the F2.5 has evolved for added efficiency and convenience. Efficient and reliable, this little wonder never ceases to amaze.

 

Yamaha’s exclusive Easy Storage Oil Retention System allows the engine to be stored on either side or on the front grip without any fear of oil leakage, assuring the engine is easy to start the first time out.

 

The built-in, see-through fuel tank lets boaters see fuel quantity at a glance, while the tank cap is designed to prevent water intrusion.

 

For simple operation, the starter knob, F-N gearshift lever and choke knob are all within easy reach.

Description

KEEP IT SIMPLE

A new Oil Filler Cap makes checking the oil level simple.

LOOKING GOOD

The updated rounded cowling design keeps the engine consistent with the look of the Yamaha outboard lineup.

LARGE TWIST THROTTLE

The large twist throttle provides a more comfortable grip for operators.

CARRY ON

A big carrying handle is designed to equilibrate the centre of gravity so the outboard can be lifted easier and maintain proper balance while being carried by one hand. The carrying handle can also be used to steer during reverse operation.

COMPACT & LIGHTWEIGHT

A single-cylinder, OHV, splash lubrication and simple TCI (Transistor Controlled Ignition) system contribute to a compact and lightweight engine.

ANTI-CORROSION PROTECTION

Yamaha’s unique YDC-30 aluminium alloy protects the engine’s exterior parts, while a zinc coating, high-quality stainless steel and 5-stage exterior coating offers long-lasting protection inside and out.
