| Features & Benefits:
Mercury EFI FourStrokes provide the ultimate in low-emissions power. Instant turnkey starting and ultra-efficient fuel management are the trademarks of our EFI FourStroke line-up.
Our 40 carb FourStrokes are easy to pull start and run quietly and efficiently. They are the perfect choice when a manual start motor is preferred.
Mercury's 40 EFI FourStrokes feature state-of-the-art fuel system components. The fuel injection system is designed to provide maximum fuel economy and reduced risk of vapour lock.
Thermoplastic materials in the intake systems of the 40 EFI make the engine only 12 pounds heavier than the carbureted version! The result: All of the benefits of EFI with very little weight increase.
Each model is tolerant of winter and summer grade fuels for convenience.
