Exciting V6 power for your offshore adventures

The sleek, good-looking F225 represents the pinnacle of Yamaha’s latest-generation marine technology. Designed for the demanding offshore environment, this light, compact V6 engine is a great powerhouse to have behind you on your watersports adventures.

For clean, smooth and quiet performance, maximum fuel efficiency and easy starting, the advanced 24-valve DOHC engine features EFI (Electronic Fuel Injection) as well as VCT (Variable Camshaft Timing). Combining technology with style, the sleek, compact design speaks for itself.

Meanwhile, at the helm, Yamaha’s ‘drive-by-wire’ electronic throttle and shift delivers the smoothest, most precise control you’ll ever experience.

24-valve, 4.2 litre 60º V6 with DOHC, EFI & VCT

An advanced, lightweight powerhead design features plasma-fused, sleeveless cylinders, double overhead camshafts (DOHC) and 4 valves per cylinder. Variable camshaft timing (VCT) delivers increased combustion efficiency across the RPM range. This combination of advanced technologies gives class-leading horsepower-per-litre.

Latest cylinder technology – large displacement with low weight

The Plasma fusion process on the cylinder walls is 60% harder than steel, but this advanced technology also offers lower weight, better cooling and less friction. The result is the largest displacement engine in the industry, yet with the lowest weight.

Electronic ‘Drive-by-Wire’ throttle/shift and Trolling RPM control

The optional Digital Network System can bring you the most comfortable, enjoyable control you’ve ever experienced, including automatic engine synchronisation in twin/triple installations and control of engine speed for trolling. A tachometer button adjusts the RPM in simple 50 RPM steps between 600 and 1000.

One-touch ‘Start/Stop’ control for multiple engines

Just pushing a single button allows the engines to be started or stopped instantly in multi-engine installations. The stylish and practical one-touch ‘Start/Stop’ control switch panel is used in conjunction with the main key switch.

Digital Network System II

The Yamaha Digital Network System II is available for all these engines. It features the latest 6Y9 gauges, a high-resolution colour LCD display, a choice of push-button ‘Start/Stop’ panels, control boxes, accessories, and an NMEA-2000® gateway. This advanced system can easily be configured for single, twin or triple engine applications.

SDS (Shift Dampener System)

First introduced for our larger V8 & V6 models, Yamaha’s patented Shift Dampener System (SDS) is a great feature that significantly reduces the ‘clunk’ sound normally associated with moving between gears. A splined rubber hub and aft washer absorb noise and vibration, in a carefully engineered solution that gives smoother, quieter gear shifts.

Yamaha Customer Outboard Protection (Y-COP) option

The optional 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.

Micro-computer ECM (Engine Control Module)

This micro-computer is the ‘brain’ hidden inside your engine. It constantly monitors data inputs and settings, ensuring smooth running and optimised ignition timings – as well as automatically activating warning lamps and protection systems. A handy computer access port allows an authorised Yamaha dealer to diagnose any problems.
