F40A
Performance. Reliability. Convenience and control. Long-term value.
These are the benefi ts you look for in a mid-range four stroke outboard. At Yamaha, we’re
constantly striving to provide all of these, and more, in every outboard we make. Continuing
this innovative tradition, Yamaha is proud to announce a new member to the Yamaha
outboard family, the F40A.
PERFORMANCE
This new four stroke is a true outboard; engineered, designed, and developed specifi cally
for the marine environment. It’s three-cylinder, single overhead camshaft design means
powerful performance in a compact package, and that performance is available in both
propeller and jet-driven models to effectively power a myriad of applications and
designs. With a newly-designed single throttle valve, a long intake track manifold,
and an Electronic Control Module these engines feature easy starting, fast
acceleration, and excellent top-end speed while still delivering the
outstanding fuel-effi ciency Yamaha outboards are known for.

RELIABILITY
Yamaha’s proven 40hp four-stroke outboard design now comes with the
addition of electronic multi-point fuel injection for easy, turn-key starting.
A large, on-engine water-separating fuel fi lter further adds to its long-term
reliability approach, as does an integral engine monitoring and warning
system and Yamaha’s renowned Ultimate Corrosion Protection System.
These features help provide the peace of mind that comes standard with
every Yamaha outboard.
CONVENIENCE AND CONTROL

Responsive Power
A single overhead camshaft provides precise valve timing
for maximum power with minimum weight. This 6-valve,
SOHC design effi ciently exchanges intake and exhaust
gases for responsive power and fuel effi ciency.
Precise Throttle Control
All air entering the engine block of the F40A is routed through
a single throttle valve, to ensure the precise amount of air
necessary for optimum power and fuel effi ciency. The air
silencer box reduces intake noise and air turbulence for
smooth, quiet operation.
POWWERFUL PERFORMANCE
Fuel Effi ciency
Three 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 effi cient combustion.
Dependable Starting
Yamaha’s new F40A features a vapor-reducing fuel return
system. Used in conjunction with Yamaha’s electronic
multi-point fuel injection, the F40A offers dependable
turn-key starting in both hot and cold conditions.
