  • An enhanced compressor wheel design provides greater airflow for enhanced power and torque and improved sound quality

Integral exhaust system designed and developed specifically for QC4v

  • Pulse separated exhaust tuning (from Mercury Racing’s expertise in high performance 2-stroke engines) improves low RPM turbocharger response

Corrosion:

  • Engine and turbocharger center sections are closed cooled for enhanced corrosion protection and engine durability
    • The charge cooler is made of a military specification alloy for excellent corrosion resistance

Advanced Electronics:

  • Propulsion Control Module (PCM) microprocessor with race specific fuel calibration
  • Digital Throttle and ShiftEngine Guardian: real-time, self-protection engine fault diagnostics and messaging
    • Single-turn “SmartStart”
    • Automatic throttle synchronization
    • “Shadow mode” (where two levers control three or four engines)
  • Sequential fuel and spark
  • 95 amp charging system (50% more output compared to competitive models) – ample power supply for today’s advanced marine electronics
    • Provides excellent fuel economy and run quality

Propulsion System:

  • Hydraulic transmission to handle the 750’s massive torque
  • Pro Finish 5 & 6-blade CNC sterndrive propellers are designed with stamina for the 1750’s massive torque and surface piercing impact
    • M8 sterndrive, packed with heavy-duty components, is designed specifically to handle the 1750’s higher torque
    • Delivers 35% more capacity than the legendary Six drive
    • Two inches shorter resulting in an overall lower center of gravity for improved handling and overall boat performance
    • Features twin pinion gear shaft design (first patented by Mercury for outboard racing back in the 1950s)
    • Innovative design splits the torque load for a high power capacity while maintaining a slim gear housing shape for hydrodynamic efficiency
    • Dry-sumped for maximum power-output
