F25

The F25 delivers the weight and performance you would expect from a two-stroke, with all of the advantages that comes with Yamaha’s industry-leading four-stroke technologies. This new generation outboard is not only an improvement on the four-stroke model it replaced, but also exceeds the all-round capabilities of Yamaha’s legendry 25 two-stroke outboard.

For the first-time in Yamaha’s four-stroke history, the F25 comes with a battery-less fuel injection option – delivering easier starts, better fuel economy and an improved overall operating performance.

Yamaha’s F25 delivers the industry’s highest power-to-weight ratio and options to suite every boating style. Choose from mechanical and/or electric start, mechanical tilt or power, trim and tilt (PTT), and a redesigned tiller handle or forward control options - now in both short and long shaft models.

With all the features and options normally only seen in Yamaha’s bigger horsepower models, the F25 punches well above its weight.

New Purpose-Built Multi-Function Tiller Handle

All F25 tiller models with power, trim and tilt (PTT) functionality, now feature a new tiller handle that is shorter and smaller, making it easier to use in tighter spaces. The PTT switch has been repositioned on the tiller handle, making it easier to reach - whether the boat is on the water, on a trailer, or the outboard and/or tiller handle are fully tilted up or down.

New Built-In Power Trim & Tilt (PTT)

Our latest F25 models now offer power, trim and tilt (PTT) functionality across both short shaft and long shaft models. PTT is available in both tiller and forward control options, giving small boat owners more choice and the option to select a premium featured engine for their hull.

Variable Trolling RPM Switch (VTS)

Standard on all F25 models, the Variable Trolling RPM Switch, located on the tiller handle or forward control gauge, allows you to set the perfect speed for trolling your favourite lure. Speed can be fine tuned, up or down, in 50 RPM increments, from 750 to 1050 RPM.

432cc Two-Cylinder

The four-valve, two-cylinder, Single Overhead Camshaft delivers sufficient torque from low to mid speed ranges for a quick response and smooth running.

Battery-Less Fuel Injection

The F25 is the first battery-less fuel injection system in Yamaha’s four-stroke range, making engine set-up more simple and convenient for pull-start models. The system takes into account engine requirements to achieve maximum engine performance including ‘first-time, every-time’ hot and cold starting.

Digital Gauges Compatible

The F25 is fully compatible with Yamaha's Digital Network Gauges (Command Link), giving you the information needed to maximise engine performance and efficiency. This engine is also NMEA2000 compatible allowing the F25 to share information with third party multi-function displays, GPS and fish finders.

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 usage reduces corrosion and extends the engines life.

High-Output Alternator

A 16 Amp high-output alternator ensures that power is always available to start the engine, even after long periods of idling or running at low revs. This not only provides extra starting power, but delivers sufficient power to run the wide array of on-board electronic devices used in modern boating. (Battery charging kit optional)

Power Trim and Tilt

Yamaha’s push-button trim control makes engine trim and tilt adjustments quick, smooth and easy, across a wide range. The negative trim settings allow for improved acceleration and the ability to bring the boat onto its plane more quickly. Optional on certain models.

Wide Span Mounting System

The large rubber mounts and the wide length between the mounts help to reduce engine vibration.

Mechanical Steering Control

The F20 has the choice between tiller or forwards mechanical control options.

Anti-Corrosion Paint System

Yamaha engines are known for their durability and high re-sale value. Part of this lies in the anti-corrosion protection. A unique YDC-30 aluminium alloy and 5-stage exterior paint coating process protects the engine's exterior parts, while high-quality, marine-grade stainless steel componentry is used through-out.

Conventional - 6Y5 Round Gauges

Yamaha’s most affordable Tachometer and Speedometer gauges offer RPM, Trim Angle, Oil Pressure, Overheat Warning, Trip Hours, Total Operating Hours, Speed, Trip Distance, Time, Fuel Level, Low-Fuel Warning and Battery Voltage/Warning.

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.

CL5 Premium Touchscreen Display

The all-new, low profile Yamaha Command Link CL5 touchscreen display is small in size but big on information, features and capability.

This display is suitable for all Yamaha Electronic Fuel Injected (EFI) engines and can monitor up to four outboards.
