F20B NEW FOR 2019!

 

 

Description

COMPACT POWER

While keeping with the two-cylinder, in-line SOHC design, Yamaha’s F20 utilizes the same award-winning engine configuration proven in Yamaha’s F25. This large 432cc displacement design is powerful, yet clean and quiet.

COMFORTABLE HANDLING

The F20’s multi-function tiller handle has a forward-mounted shift control within easy reach of the driver, as well as a large throttle twist-grip for added comfort. The tiller also provides a wide steering angle of 45 degrees in each direction for more nimble handling.

BACK UP MANUAL START

For added peace of mind, the F20 offers manual back up start on all electric start models.

COMPATIBILITY

The convenience of the new Electric Start option brings full compatibility with Yamaha’s advanced Digital Network System, which includes the availability of clear, stylish gauges that offer the driver a comprehensive selection of running data and engine performance information.

CHARGED UP

The F20 features an alternator that produces up to 16 amps of power. That’s 60 percent more output than the previous generation F20. There is ample electrical power for battery charging with plenty to spare for additional electronic equipment.

EASY DOES IT

An easy access hose connector on the lower cowling allows you to flush salt and dirt from the waterways without starting the engine – a quick, simple way to reduce corrosion and extend the life of your 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.
