The Mercury Racing Dual Cal 1550/1350 sterndrive features an advanced control system which enables the operator to switch engine power level via an electronic key fob. The Race key fob turns the engine into a pure bred race machine – pumping out one thousand five hundred and fifty horsepower on 112 AKI race fuel. The Pleasure key fob is selected when a more leisure ride is in order, creating 1350 h.p. on 91 octane (98 RON) fuel. Both fuel calibrations provide maximum torque and efficiency and are designed to optimize the engine performance at each power level.
A short, surface-piercing gearcase allows the engines to be mounted two inches deeper in the boat, which lowers the center of gravity, improving boat handling and overall performance. It also provides more flexibility in boat hatch styling. The M8 features twin-pinion drive and robust internal components rated to handle up to 1600 lb. ft of torque and 1600hp. Its dry sump design reduces parasitic power losses. A standard active anode provides enhanced corrosion resistance.
Digital Zero Effort Controls replace the lag and hesitation of traditional throttle and shift cables with digital precision, resulting in smooth shifting and instant throttle response. Ergonomic design features short-throw levers for effortless shifting and ultra-fast throttle response, and the robust stainless-steel levers offer unmatched durability in the offshore environment. Digital Zero Effort Controls can provide automatic throttle synchronization and shadow mode for up to six engines (where two levers operate six engines).
STERNDRIVE CNC PROPELLERS
Pitch, diameter, and rake are perfectly true on every Mercury Racing CNC propeller to ensure that lift, handling, and speed characteristics are absolutely consistent. Thousands of pitch, rake and diameter combinations are available to dial in the maximum performance of almost any high-performance boat. Each CNC Cleaver propeller is custom made to order.
