Yamaha's 9.9F has been designed to be easy to transport, with plenty of power for great performance on small boats. The 246cc two cylinder engine delivers reliability that is second to none along with excellent fuel efficiency from the utilisation of loop charged fuel induction. Yamaha's precise engineering and leading edge manufacturing techniques allow the 9.9F to run a 100:1 pre mix oil ration for smoother, cleaner operation.
Trusted two-cylinder two-stroke design is durable, powerful and extremely reliable.
100 to 1 Fuel Oil Ratio
Superior manufacturing techniques allow a leaner oil mixture, reducing smoke, odour and engine carbon build-ups while also reducing oil consumption and running costs.
Yamaha's unique marine alloy, YDC-30, has been developed exclusively to handle the harshest of marine environments and is the result of years of Yamaha research and testing. YDC-30 delivers superior anti-corrosion properties that Yamaha outboards are legendary for.
Ergonomic Carry Points
Ergonomically placed carry points located near the motor’s centre of gravity allow easy carrying and mounting.
Loop-charged scavenging creates a circular fuel flow for efficient transfer of exhaust gas and even distribution of the air-fuel mixture. The result is greater combustion efficiency for excellent performance and better fuel economy.
Maintenance Free CDI Ignition
The capacitor discharged ignition system provides strong spark and precise timing, preventing plug fouling, improving starting performance and reducing maintenance.
Yamaha uses strategically placed aluminium and zinc anodes for maximum corrosion protection. These anodes are even larger than necessary, ensuring total effectiveness.
Shallow Water Drive
The shallow water drive system allows the engine to be quickly set and operated at a tilted angle allowing safe navigation through shallow water.
