Yamaha Customer Outboard Protection (Y-COP) option
Yamaha's unique Y-COP immobiliser system is a simple, easy to use and highly effective option – the neat and simple remote control locks and unlocks the engine 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.
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.
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.
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.
Special high gear ratio 2.33
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.
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.
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.
