THE DI ADVANTAGE
The smaller the fuel particle the better the combustion.
Our Direct Injection system sends a mist of microscopic,
atomized fuel and air particles directly into the cylinder.
Eighty-nine times smaller than the diameter of a human
hair, these fuel particles burn quicker, cleaner and more
completely producing fewer emissions, better fuel
economy and more responsive performance.
CHAMPIONSHIP-CALIBER PERFORMANCE
With a long history of proven, powerful performance,
OptiMax Pro XS was designed to rule the water.
Rooted in Mercury Racing, OptiMax
Pro XS tapped into Mercury’s tradition
of speed, power and durability.
J.D. Power and Associates ranked OptiMax
highest in customer satisfaction the past three years.
