Mid-Range

Yamaha proudly announces a new addition to its mid-range four stroke stable; the F70. Using advanced features and technology to make it extremely light yet very powerful, it is the ideal outboard for a myriad of lightweight shing boats and an outstanding alternative to Yamahas soon-to-be-retired 90hp two stroke (effective 12-31-2009). Featuring the lightest weight and highest horsepower-per-liter-of-displacement in the 70hp class, the Yamaha F70 takes advantage of the leading edge of technology while maintaining the fuel-efcient, smooth, and quiet operation Yamaha four strokes are known for. And it has benets like Yamahas available Multifunction Tiller Handle or our Command Link System, which let you harness its Variable Trolling RPM capability.
The new Yamaha F70. Big-league technology in a very light weight, fuel efcient outboard.
Best-in-Class Horsepower-per-Liter advanced 16-valve, single overhead camshaft (SOHC), in-line 4 cylinder engine design. Lightest Weight In Class at 260 pounds, its lighter than all four stroke and two stroke outboards of similar horsepower.* Remarkably Responsive a single throttle valve works in concert with a tuned, long track intake system and high-ratio gearcase. Outstanding Fuel Efciency Yamahas Multi-point Electronic Fuel Injection System and dependable ECM microcomputer engine control. Proven Reliability designed, built, and extensively tested to Yamahas stringent standards for reliability. Smooth, Dependable Mechanical Shifting and Throttle works with all Yamaha binnacle and most side-mount mechanical control boxes. Operator Convenience compatible with conventional analog or optional Command Link gauges, for even more up-to-the-instant information. Quiet, Smooth Operation Yamahas labyrinth exhaust and Long-Span Mounting System combines with a stylish yet functional exterior. Ease of Service and Lasting Value computerized Yamaha Diagnostic System (YDIS), Ultimate Corrosion Protection System, and water-draining air intake cowling. Peace of Mind advanced engine warning and protection system and standard three year pleasure or government limited warranty.

An advanced powerhead design features a single overhead camshaft (SOHC), yet with four valves per cylinder, for maximum power and efciency. 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-liter of engine displacement than competitive outboards, both four stroke and two stroke direct-injected.

From the specially designed engine block to the two-piece upper case, every ounce of weight-savings has been realized for maximum performance without sacricing durability. Yamahas new F70 is not only the lightest four stroke 70 horsepower outboard, its even lighter than competitive two stroke direct-injected outboards.

POWER AND PERFORMANCE F250 SPECIFICATIONS PRECISE THROTTLE CONTROL MAXIMUM POWER AND EFFICIENCY
All air entering the engine block of Yamahas new F70 four stroke is routed through a single throttle valve, to ensure the precise amount of air necessary for optimum power and fuel efciency. 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.
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 efcient combustion.

HOLE SHOT AND ACCELERATION
MORE POWER, CLEANER EMISSIONS
Yamahas 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.
The F70 derives every bit of power available from the fuel by using Vapor Reduction and Vapor Burning Systems. By eliminating vapor from the fuel rail and re-routing it back to the Vapor Separator Tank, only fuel is injected in the cylinders for better combustion and power. A fuel vapor valve prevents fuel vapors from escaping to the atmosphere when the outboard is not running, and re-routes fuel vapors through the intake when the outboard is running. This helps achieve maximum fuel efciency and minimum emissions.
RELIABILITY AND DURABILITY F250 SPECIFICATIONS PROTECTION FROM THE ELEMENTS QUIET, YET STRONG
The new F70 features a new outer cowling design with an intake air drain system, to easily and efciently 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 engines intake, for maximum reliability.
Yamahas 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

DRYER OPERATION
All new F70 outboards feature a large, on-engine water separating fuel lter with a water sensor. Used in conjunction with Yamahas optional boat-mounted 10-Micron Water Separating Fuel Filter, it helps separate water and contaminants from the fuel before they can reach the outboards other lters and fuel injectors.
Yamahas 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.
CONVENIENCE AND CONTROL F250 SPECIFICATIONS PRECISE TROLLING CONTROL MORE INFORMATION
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 engines 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 efcient and effective operation. Available in square or round style to t a wide range of tastes and applications.
TILLER HANDLE CONVENIENCE

SMOOTH AND QUIET

Yamahas award-winning optional Multifunction Tiller Handle offers the benets 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, its ergonomically-designed to provide maximum control with maximum comfort.
Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet for unbelievably smooth and quiet operation.
