2024 Yamaha Outboards F40

2024 Yamaha Outboards F40 LEHA

Enhanced reliability, exceptionally smooth and quiet operation, outstanding fuel efficiency, maximum performance and convenience. All combine to make the new Yamaha F40 an incredibly powerful and versatile value.

Features may include:

• 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.

• 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.

• 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.

• 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.

• Yamaha improved their legendary Ultimate Corrosion Protection System for the F40A. 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.

• 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.
