Compact, Powerful and Built for Versatility
The Yamaha F9.9 9.9HP Four-Stroke Outboard offers an excellent combination of power, fuel efficiency and reliability in a compact, portable package. Ideal for small aluminium boats, inflatables, yacht tenders and recreational fishing boats, the F9.9 delivers dependable Yamaha performance with the extra power needed for larger tenders and small runabouts.
Powered by Yamaha's proven 212cc twin-cylinder four-stroke engine, the F9.9 delivers smooth, quiet operation with excellent low-to-mid-range torque. Its twin-cylinder design provides a noticeable improvement in refinement over smaller single-cylinder outboards, making longer trips more comfortable.
Yamaha's PrimeStart™ system takes the hassle out of starting, automatically managing the cold-start process without the need for a conventional choke. An automatic decompression system also reduces the effort required when pull-starting the engine.
Despite its additional power, the F9.9 remains relatively easy to handle. Comfortable carrying grips, a folding tiller handle and specially designed resting pads make transporting and storing the engine straightforward.
The F9.9 also features a three-position shallow-water drive system, ideal for exploring tidal creeks, estuaries and sheltered bays where water depth can be an issue.
Whether you're heading ashore from your yacht, exploring the Bay of Islands or enjoying a day fishing, the Yamaha F9.9 offers the performance and reliability you'd expect from Yamaha.
