An advanced powerhead design features a single overhead camshaft (SOHC), yet with four valves per cylinder, for maximum power and efficiency. Total intake valve area is increased 17%, while the pistons and valves are up to 10% lighter (when compared to our T60 model), giving it substantially more horsepower-per-litre of engine displacement than competitive outboards, both four stroke and two stroke direct-injected.
Lightest Weight in Class
From the specially designed engine block to the two-piece upper case, every ounce of weight savings has been realized for maximum performance without sacrificing durability. Yamaha’s new F70 is not only the lightest four stroke 70 horsepower outboard, it’s even lighter than competitive two stroke direct-injected outboards.
Precise Throttle Control
All air entering the engine block of Yamaha’s new F70 four stroke is routed through a single throttle valve, to ensure the precise amount of air necessary for optimum power and fuel efficiency. It then enters each cylinder through individual long intake tracks, which are ‘pulse tuned’ to provide air at the precise volume and timing for maximum density and power.
Maximum Power and Efficiency
Four individual compact electronic fuel injectors deliver the exact amount of fuel needed for optimum performance and economy. Controlled by the Engine Control Module via input from an array of on-engine sensors, their location just above the intake valves enhances fuel atomization, resulting in more efficient combustion.
HOLE SHOT AND ACCELERATION
Yamaha’s F70 provides outstanding hole shot and acceleration thanks in part to an advanced sensor that allows maximum safe ignition timing and a gearcase featuring a high 2.33:1 gear ratio, with specially hardened pinion, forward, and reverse gears for increased durability.
More Power , Cleaner Emissions
The F70 derives every bit of power available from the fuel by using Vapour Reduction and Vapour Burning Systems. By eliminating vapour from the fuel rail and re-routing it back to the Vapour Separator Tank, only fuel is injected in the cylinders for better combustion and power. A fuel vapour valve prevents fuel vapours from escaping to the atmosphere when the outboard is not running, and re-routes fuel vapours through the intake when the outboard is running. This helps achieve maximum fuel efficiency and minimum emissions.
Protection from the Elements
The new F70 features a new outer cowling design with an intake air drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that help trap and drain water before it enters the engine’s intake, for maximum reliability.
Quiet, Yet Strong
Yamaha’s F70 four stroke outboard utilizes a Long Span Mounting System, which uses large specially constructed rubber engine mounts placed as far apart vertically and horizontally as practically possible. Smooth and quiet operation, yet with strength and durability, is the result.
LARGE WATER SEPARATOR
All-new F70 outboards feature a large, on-engine water separating fuel filter with a water sensor. Used in conjunction with Yamaha’s optional boat-mounted 10-Micron Water Separating Fuel Filter, it helps separate water and contaminants from the fuel before they can reach the outboard’s other filters and fuel injectors.
Yamaha’s large anti-splash plate, standard on F70 models, helps keep water from splashing up between the leading edge of the outboard and the boat, resulting in a much dryer ride. Located on the front of the lower mid-section just above the lower unit, it excels in applications where the outboard is normally run deep in the water, such as pontoon boats.
PRECISE TROLLING CONTROL
By just pressing a button on the Command Link® tachometer or the VTS – switch on the optional Multifunction Tiller Handle, the operator can adjust the engine’s trolling speed from 620 ~ 900 rpm in 50-rpm increments. This helps provide precise and consistent trolling speeds in wide array of conditions.
Optional Command Link gauges offer a wealth of information to the operator in order to help provide efficient and effective operation. Available in square or round style to fit a wide range of tastes and applications.
TILLER HANDLE CONVENIENCE
Yamaha’s award-winning optional Multifunction Tiller Handle offers the benefits demanded most in a tiller control. From its front-mounted gear shift and ignition key switch controls, to the easy-to-use Variable Trolling RPM Switch, it’s ergonomically designed to provide maximum control with maximum comfort.
SMOOTH AND QUIET
Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet for unbelievably smooth and quiet operation.
