Model Description


Easy to carry. Even easier to enjoy.


Discover engines so light that they’re easily carried to the shore or onto the deck of your main boat. The F4, F5 and F6 are convenient to store and use, offering the power you need to hit the water with confidence.


Their compact size, large carrying handles and built-in fuel tanks enhance their portability – and start-up is easy with Yamaha’s CDI Ignition System. On the water, low fuel consumption, simple controls and low noise and vibration levels come as standard. As with any Yamaha, reliability is assured.


Whether you’re a fishing enthusiast looking for an easy way to get on the water, or a yacht owner seeking a handy auxiliary, the F4, F5 and F6 offer ideal solutions.
