Powerful, efficient and reliable, the F40 combines the benefits of Yamaha’s Multi-Point Electronic Fuel Injection (EFI) system, with a Micro-Processor Controlled System to deliver reliable turnkey hot and cold starting, improved fuel economy, incredible mid-range torque, lower emissions, and an overall smoother and quieter operation.
The compact 747cc 3-cylinder, marine engine delivers the optimal balance of power, torque and refinement for exceptional versatility in both forward or tiller handle control applications. The forward control option can be matched with digital gauges, including Yamaha's feature packed Command-Link system. While the optional Multi-Function Tiller Handle comes standard with trim, shift, and throttle controls, as well as ‘start-in-gear’ protection and warning horn alerts, all integrated into the ergonomic handle.

Features
747cc 3-Cylinder Engine
The six-valve, three-cylinder, single overhead camshaft marine engine delivers superior efficiency in the transfer of intake and exhaust gasses throughout the RPM range.
Power Trim and Tilt
Yamaha’s push-button trim control makes engine trim and tilt adjustments quick, smooth and easy, across a wide trim range. The negative trim settings allow for improved acceleration and the ability to bring the boat onto the plane more quickly.
Variable Trolling Control
Yamaha’s variable trolling control allows you to precisely adjust the engine’s idling speed from 650 to 900 RPM in 50 RPM increments. The ability to finely tune the trolling speed allows fisherman to perfect their lure presentation when chasing different species of fish.
Electronic Fuel Injection
The Multi-Point Electronic Fuel Injection (EFI) system, in conjunction with the Engine Control Module (ECM), injects the right amount of fuel into the combustion chamber at the optimum timing. This results in ‘first-time, every-time’ hot and cold starting, improved fuel efficiency and excellent throttle response.
Fresh Water Flushing System
Simply connect a hose to the easy access connector to flush salt and dirt from the outboard without having to run the engine. Flushing the engine after each use reduces corrosion and extends the engines life.
Long Intake Manifold
The long intake manifold is designed to increase torque at low speeds for better acceleration and efficiency.
Long Span Mounting System
The large rubber mounts and the long vertical length between the upper and lower mounts help to reduce engine vibration.
Mechanical Steering Control
The F20 has the choice between tiller or forwards mechanical control options.
Prime Start
Exclusive to Yamaha, Prime Start makes starting a Yamaha outboard as easy as starting a car. It allows the engine to be started cold by automatically controlling the engine ‘warming up’ process - eliminating the need for a conventional choke. You no longer need to ‘warm up’ your engine by revving it in neutral.
Rigging Componentry
Conventional - 6Y5 Round Gauges
Yamaha’s conventional digital multi-function gauges provide the real-time data required to maximise outboard performance and fuel efficiency. The two and three gauge illuminated display options provide rpm, trim, oil, speed, distance, time, overheating, battery, fuel economy/flow/consumption stats.
Command Link - 6Y8 Round Gauges
Using Local Area Network (LAN) technology, these digital round gauges provide accurate and real-time tachometer, speed and fuel management stats, including fuel flow/consumption/economy (up to two tanks), trim level, battery voltage, push button trolling speed adjustments and more.
Command Link - 6YC High Definition Gauge
This high definition, colour display uses Local Area Network (LAN) technology to deliver accurate and real-time stats for single and twin engine setups. The customisable day/night gauge delivers information on fuel flow/ economy/ consumption, trim level, battery charge, speed, push button trolling and more.
703 Side-Mounted Control
One of Yamaha's best selling controls, this mechanical remote offers comfort, simplicity and flexibility. With its new ergonomic grip, reversible right-hand or left-hand installation, and convenient trim and tilt operation, this control offers all-round functionality and value.
6x3 Concealed Side-Mounted Control
With its stylish chrome finish and ergonomic design, this mechanical control not only looks good, but provides effortless one-hand operation. The trim and tilt switch is comfortably located on the handle and features easily accessible neutral warm-up controls and externally adjustable throttle friction.
704 Premium Single Binnacle Control
This highly-polished, stylish looking, top mounted control allows for effortless one-handed control. The ergonomic design features a thumb operated trim and tilt switch built into the handle, as well as shift and throttle control functions, for convenient and comfortable operation.
Genuine Yamaha Propellers
Prop choice makes a huge difference to outboard acceleration, top-end speed, handling and fuel efficiency. That is why Yamaha continues to push the technological boundaries in the design and development of our leading range of high performance props - ensuring every Yamaha outboard performs at its peak.
Alloy White J Series
These props deliver Yamaha's high-quality design and performance in a low-cost, lightweight propeller. They offer a good all-round choice for Yamaha outboards, coming in a wide range of sizes and pitches to suit every power requirement.
Multifunction Tiller Handle
With the latest technologies, ergonomic design and features, Yamaha's optional Multi-Function Tiller Handle delivers effortless control, maneuverability and comfort. Trim, shift, throttle, stop switch, variable trolling and integrated overheating and low oil pressure warning alerts are all built into the handle.
Remote Control Security System
Yamaha's optional Customer Outboard Protection (Y-COP) engine immobiliser system is easy to use and highly effective in stopping unauthorised start-ups when your boat is unattended.
