MERCURY RACING 600 SCI STAGE 3

The Whipple Stage 3 system boasts even more power than stage 2 system by coupling a Stage 3 performance calibration with a Whipple high-flow flame arrestor element. The Whipple high-flow flame arrestor replaces the stock paper gauze style arrestor with a stainless steel mesh arrestor for increased airflow. This system helps boost the engines output by more than 170HP* and 140 pounds of torque*. Whipple also increases the low rpm power range for significant decrease in plane time and a healthy gain in acceleration. The factory rpm limiter is also increased, giving customers the ability to greatly increase top speed MPH while running original props. The stock RPM limit of 5400 is modified to 5850rpm where peak power ends. 

Key features:

• Hi-performance PCM calibration with MPH gains of 8-12mph**
• Intercooler water re-route
• High-flow billet flame arrestor
• Increased horsepower for increased top speed MPH
• Increased low-speed torque for decreased plane time
• Increased low, mid and high speed torque for better acceleration and throttle response
• Increased spark at low and mid speeds for increased engine efficiency
• 5850 RPM limit vs. stock 5400 RPM limit giving increased propping range and increased horsepower
• 91 octane safe (RON+MON)/2
• 10-Rib Gates serpentine belt
• Stock idle, starting and drive-ability is maintained
