Mercury 40 EFI Boat Motor
Three-cylinder four-stroke engines with electronic fuel injection, remote control and electric starting. The EFI system (Electronic Fuel Injected) brings to perfection even without this excellent technical characteristics of these four-stroke engines. Electronics measures fuel exactly, taking into account besides frequency of crankshaft rotation and size of motor loading, temperature of surrounding air, temperature of cylinder crankcase, piston position, pressure in an inlet collector. All this allows Mercury 40 EFI engines to be even more economical, than ordinary four-stroke engines. In addition, motors with the EFI injection system differ with reliable starting and steady work even on the smallest turns in any temperature range. Low level of noise and pollution of the environment taken to the minimum - another plus for Mercury 40 EFI.

Due to the compatibility with the SmartCraft system, which represents complete information of the motor work parameters and technical condition, even unprepared man can steer Mercury 40 EFI. If some of parameters exceed a norm in case of owner carelessness or inexperience, the ECM555 electronic control block will make a warning signal and then will correct the motor operating mode. All of engines are equipped with alternators of 223 W. The cooling system is supplied with thermostat and pressure regulator, which support the stable temperature conditions of engine work. The fuel system has also liquid cooling, that`s why Mercury 40 EFI owners never have such problem, as fuel boiling and formation of steam corks, resulting in interruptions of motor work. It doesn`t matter how intensively they exploit their engines, it works good. An exhaust is made through propeller hub. Construction of suspension bracket has remote control incline regulation. Mercury 40 EFI are supplied with standard (381 mm) and long (508 mm) dead-wood. The button of emergency stop is included in standard kitting-up of all engines.
