Offering unbeatable versatility, the lightweight F70 will power a wide range of boat types, so it’s equally at home when you’re working, or if you’re out to experience the fresh air and fun of leisure boating and watersports. In fact, the F70 is the lightest, most powerful 4-stroke in its class.
For cleaner performance, maximum fuel efficiency and easy starting, the powerful 16-valve SOHC engine features EFI (Electronic Fuel Injection) and Yamaha’s unique PrimeStart™ system. Compatibility with Yamaha’s Digital Network Gauges delivers precise control too. Sleek and stylish too – your F70 is sure to attract admiring glances from everyone – whether aboard or on the shore.
For leisure, pleasure or hard commercial work, the exciting F70 delivers you the perfectly proportioned, lightweight power package. The very latest Yamaha marine technologies are built into the F70, with revolutionary engine layouts and ingenious intake and exhaust systems. Supreme efficiency is assured by micro-computer controls which monitor every aspect of engine performance, from fuel mixture and combustion efficiency to maintenance scheduling. A major focus of Yamaha’s engine development is on clean-burn technologies that help preserve our environment, yet don’t compromise on power, performance or usability.
16-valve, in-line 4 cyl, SOHC, EFI
The F70’s advanced, lightweight powerhead design features a single overhead camshaft (SOHC) with four valves per cylinder, for maximum power and efficiency. A large intake valve area with lightweight pistons and valves give class-leading horsepower-per-litre.
It’s not just fast – it’s tough too
The Yamaha F70 provides outstanding ‘out of the hole’ acceleration, thanks in part to the lower gearcase design which features a high gear ratio of 2.33:1. The extra toughness comes from the fact that all gears (Forward, Reverse and pinion) are specially hardened for increased durability.
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 or unlocks the engine’s ignition system at the push of a button. This prevents your outboard engine being taken for an unauthorised joyride, offering you peace of mind when leaving your boat unattended.
Yamaha Digital Network Gauges
The F70 is 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.
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.
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 F70 has power-to-weight ratios that make it the ideal choice for a wide range of boats.
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.
EFI system for greater efficiency and economy
Electronic fuel injectors deliver the exact amount of fuel needed for optimum performance and economy. Controlled by the ECM via input from an array of engine sensors, their location just above the intake valves enhances fuel atomisation, resulting in more efficient combustion.
