    T25

    Yamaha’s range of high-thrust outboards have been specifically designed to provide the extra grunt you need to move big loads such as sailboats and heavy pontoons. These dual-thrust four-stroke engines produce twice the thrust of comparable two-strokes within the 2,000 to 3,000 RPM range, while delivering Yamaha’s the legendary reliability, durability, and efficiency that Yamaha Outboards are renown for.

    The key mechanical difference between the FT25 and the standard four-stroke platform is the use of a higher gear ratio. This allows the FT25 to spin a much larger propeller, generating more power to the water and resulting in less slippage. The FT25 comes standard with Yamaha’s patented Dual Thrust propeller that provides maximum traction in both forward and reverse, by re-routing the exhaust in the opposite direction when in reverse. 

    Features & Rigging Componentry

    498cc Two-Cylinder High Thrust

    The large cubic-capacity, four-valve, twin-cylinder, single overhead camshaft marine engine delivers sufficient torque from low-to-mid speed ranges, for quick response and for pushing big loads. This engine has been engineered with a counter balancer to reduce engine vibration.

    Dual Thrust Propeller

    Yamaha's large-diameter, low-pitch dual-thrust propellers are designed to give instant power in both forward and reverse, by redirecting exhaust gases way from the propeller, reducing reverse ventilation and generating more power to the water. This design increases forward thrust by up to 60% and reverse thrust by up to 70%.

    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.

    Anti-Splash Plate

    An optional extended anti-splash plate can be fitted to the F25 to mitigate splash-back.

    High-Output Alternator

    A 12-Volt 13.5-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.   

    High Gear Ratio

    All Yamaha high-thrust outboard models utilise a lower-mounted gear case design, featuring a high gear ratio. The gears are specially hardened to withstand the toughest working conditions, for long-term durability.

    Large Diameter Propeller

    A higher gear ratio of 2.42:1 allows the FT25 to drive a large diameter propeller. This improved capacity enables the outboard to push greater volumes of water and generate increased thrust.

    Long Intake Manifold

    The long intake manifold is designed to increase torque at low speeds for better acceleration and efficiency.

    Mechanical Steering Control

    The FT25 engine is available as a mechanical forward-control option, suitable for center console and side console boats.

    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.

    Anti-Corrosion - 5 Stage Paint System

    Yamaha engines are known for their durability and high re-sale value. Part of this lies in their anti-corrosion protection. A unique YDC-30 aluminium alloy and 5-stage painting process protect the engine's exterior parts, while high-quality marine grade stainless steel is used on all critical internal componentry - for long-lasting protection. 

    Prime Start

    Exclusive to Yamaha, Prime Start makes starting your 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. This means you no longer need to ‘warm up’ your engine by revving it in neutral.

    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 Dual Thrust Series

    Designed for sailboats and other large displacement craft, Yamaha’s dual thrust props are built to push heavy loads through the water. The hub is carefully designed to redirect exhaust flow away from the blades, cutting through clean water for higher efficiency and better acceleration.
