Dual Cal 1350

Dual Cal 1350

The Dual Cal 1350 sterndrive features the Mercury Racing-exclusive dual fuel calibration technology, with its power output controlled via interchangeable electronic key fobs at the dash. The engine pumps out its advertised one thousand three hundred and fifty horsepower on 91 octane fuel when the 1350 horsepower fob is engaged. Engaging the 1100 horsepower fob reduces the octane requirement to 89 or rec 90 to allow operation in areas where premium fuel availability is unknown. Consumers are responsible for making sure they have the correct fuel grade in their tank when running in 1350 mode. Both fuel calibrations provide maximum torque and efficiency and are designed to optimize engine performance at each power level.
