F100 // F80
Technology the world trusts
Whether you're a recreational boat owner or a busy professional, choose the engine that will help you get more out of your boat.
Every engine in the Yamaha range uses the very latest Yamaha marine technologies, engine layouts and ingenious intake and exhaust systems. Efficient performance is ensured by a system of micro-computer controls that precisely monitor the engine – from fuel mixture to combustion efficiency and maintenance scheduling.
And, without compromising on power, performance or usability, our specially designed marine engines also help preserve the environment through the use of pioneering clean-burn technologies.
16-valve DOHC engine layout
The DOHC (Double Overhead Camshaft) layout, with its increased cylinder capacity and large valves, results in optimum valve actuation, delivering improved acceleration and performance. Yamaha's latest 4-stroke technology combines this with advanced intake and exhaust system designs – and our unique multi-point Electronic Fuel Injection (EFI).
Large single throttle valve
This innovative system controls the flow of air to all four cylinders, pulse-tuning it before it reaches the injectors of the EFI system. The air is therefore delivered with ultimate precision, according to the demands of the driver and the combustion conditions.
Micro-computer ECM (Engine Control Module)
A reliable micro-computer is the 'brain' of your engine. By constantly monitoring all data inputs and settings, it helps to ensure smooth running and optimised ignition timings – as well as automatically activating warning and protection systems. A handy access port lets authorised Yamaha dealers easily diagnose any problems.
Digital Network Gauges
The F80 and F100 are compatible with Yamaha’s Digital Network Gauges, giving you the information needed to maximise engine performance and efficiency, including a Multifunction Tachometer with RPM, Hours Run, Trim Angle, Oil Pressure, Warning lamps and Variable RPM control - and a Speed/Fuel Management Gauge with Speed, Tank Capacity and Fuel Economy.
Yamaha Customer Outboard Protection (Y-COP)
The Y-COP immobiliser system is simple, easy to use and highly effective – a neat and simple remote control locks and unlocks the engine at the push of a button. This prevents your outboard engine being taken for any unauthorised joyrides, offering you peace of mind when leaving your boat unattended.
Wide Range Power Trim & Tilt
Discover the versatility and power of a Yamaha engine. Quick response, via push-button control, makes trim and tilt adjustments swift, smooth and easy. The confidence-giving handling control provided by the wide trim range includes negative trim settings to improve acceleration and help bring the boat onto the plane quickly.
