Guaranteed peace of mind!
Yamaha F40 engines are designed to be easy to install and use while providing reliable power.
Yamaha's Electronic Fuel Injection system (EFI) delivers impressive power at high speeds, plus real mid-range punch and torque – along with outstanding fuel economy. PrimeStart™ makes starting up as effortless as with your car – and since this is a Yamaha, this means first time, every time. Our unique Wide Range Power Trim & Tilt system lets you take full control.
Finally, for complete peace of mind, your motor is protected by the Y-COP system (Yamaha Customer Outboard Protection), which immobilizes your outboard motor with the push of a button.
Increased reliability, smooth operation and silent as an oyster, low fuel consumption, impeccable performance and convenience ... and this is only the beginning with this F40 outboard by Yamaha. You will be delighted by its power and versatility!
To better preserve the marine environment, Yamaha uses novel technologies for clean combustion that do not alter the qualities, power or performance of their motors.
RESPONSIVE POWER
A single overhead camshaft provides precise valve timing for maximum power with minimum weight. This 6-valve, SOHC design efficiently exchanges intake and exhaust gases for responsive power and fuel efficiency.
PRECISE THROTTLE CONTROL
All air entering the engine block of the F40 is routed through a single throttle valve to ensure the precise amount of air necessary for optimum power and fuel efficiency. The air silencer box reduces intake noise and air turbulence for smooth, quiet operation.
FUEL EFFICIENCY
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 efficient combustion.
DEPENDABLE STARTING
Yamaha's new F40 features a vapour-reducing fuel return system. Used in conjunction with Yamaha's electronic multi-point fuel injection, the F40 offers dependable turnkey starting in both hot and cold conditions.
LONG TERM VALUE
Yamaha improved their legendary Ultimate Corrosion Protection System for the F40. Yamaha's proprietary alloys, ACP-221 paint process, and freshwater flush device are just the start. Multiple sacrificial anodes in and on the powerhead, mid-section, and lower unit, a special ACP-221 paint process, and a specially painted and treated exhaust system means better long-term protection and maximum value.
ADVANCED TECHNOLOGY
All F40 models are equipped with an Engine Control Module that interfaces with Yamaha Diagnostic System software. This provides a view of selected past and current running conditions to help technicians provide a complete and accurate diagnosis.

All F40A outboards feature a large, on-engine water separating fuel filter with a water sensor.
