OptiMax

OptiMax 2-stage direct-fuel-injection (DFI) technology atomizes fuel, resulting in a more complete fuel burn, which in turn results in complete combustion for quick and easy starts, better performance, lower emissions, and maximum fuel efficiency. Many OptiMax engines are more fuel efficient than comparable four strokes.

Mercury's two stage DFI design works as follows. Fuel is blown into a fine mist as air is forced through it by an air compressor. This mist is ignited by the spark plug, and completely burned, reducing emissions and increasing fuel efficiency. This in addition to its tremendous power to weight ratio makes OptiMax a great choice for any government agency.

OptiMax's DFI technology provides turn key starts, better hole shot, low-end torque, and top-end speeds. It allows OptiMax to meet and exceed EPA emissions standards and the California Air and Resource Board (CARB) 2 and 3 star ratings.

The entire OptiMax line is compatible with SmartCraft systems, Engine Guardian, and Total Vessel Intelligence. 200 and 225 horsepower OptiMax's are also DTS compatible.
