  • Ultra-smooth 4-cylinder refinement - with EFI

    Whether strokes or cylinders, Yamaha understands the power of Four! Which is how the world's pioneer in 4-stroke technology has brought added refinement to the 4-cylinder configuration with a powerful long stroke design for the EFI-equipped F50 - to deliver ultra-smooth, useable power with low noise and vibration levels.

  • Yamaha Digital Network Gauges

    The F50 is compatible with our Digital Network Gauges, which deliver 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.

  • Variable Trolling RPM control

    With the press of a button on the optional Digital Network's Tachometer – or via the variable trolling RPM switch on the optional multi-function tiller handle – the driver can adjust the engine speed for relaxed trolling, in precise steps of 50 RPM, between 620 and 900 RPM.

  • 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 across a wide trim range. The negative trim settings are particularly useful to improve acceleration and bring the boat onto the plane quickly.

  • Compact shape and solid one-piece top cowling

    With the advanced design and modest overall dimensions of this 4-cylinder unit, our engineers have produced a remarkably compact 996cc powerhouse, but with a low weight that is comparable to a conventional 3-cylinder engine. So the F50 has a power-to-weight ratio that makes it the ideal choice for a wide range of boats.

  • Yamaha Customer Outboard Protection (Y-COP) option

    The Y-COP immobiliser system is simple, easy to use and highly effective – a neat and simple remote control locks and unlocks the engine's ECM 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.

  • Advanced warning systems

    Yamaha engines are renowned for their reliability and for how well they hold their value. The comprehensive warning systems on this engine measure oil pressure, engine temperature and other key variables to provide clear audio/visual warnings of any problems. If a fault occurs, RPM are automatically reduced, to protect your engine as you head for shore.
