Mercury Racing 600 SCI Whipple Stage 2 Performance Kit

MERCURY RACING 600 SCI
WHIPPLE STAGE 2 PERFORMANCE KIT

The Whipple Stage 2 Performance Kit for Mercury Racing 600 SCI applications builds on the Stage 1 calibration package by adding supporting hardware for increased boost, improved intercooler system performance, and stronger overall power gains. This package includes a Stage 2 PCM calibration, Stage 2 supercharger pulley, and a bolt-on intercooler water re-route upgrade.

The Stage 2 package is listed to increase engine output by more than 150 HP and 130 lb-ft of torque under Whipple test conditions. Whipple also increases low-RPM power to help reduce plane time and improve acceleration. The factory RPM limit is raised from 5400 RPM to 5850 RPM, giving customers a wider propping range and additional top-speed potential when the boat, prop, conditions, and setup support it.

• 5850 RPM limit compared to stock 5400 RPM limit
• Designed for 91 octane fuel using the (R+M)/2 rating method
• Maintains stock-style idle, starting, and driveability

Calibration Service Process

The PCM must be removed and sent to Whipple Superchargers for calibration service. Include a copy of the receipt and any relevant engine, boat, fuel, prop, PCM, pulley, water system, and setup details with the PCM. Typical turnaround time is 7-10 days.

New PCM units may be available upon request. Verify PCM compatibility, engine model, fuel octane, current calibration, pulley setup, intercooler water system configuration, and complete installation requirements before ordering.

Performance note: Power levels can vary from engine to engine. Whipple performance results were achieved under controlled conditions, and all applications can vary. Boat speed, plane time, and acceleration results depend on boat design, propping, atmospheric conditions, operating environment, driver input, and the complete engine package. MPH gains are helpful reference points and are not guaranteed.

Application note: This is a performance kit with calibration and hardware components. It does not diagnose or repair mechanical, fuel system, ignition, sensor, cooling system, or general running issues.
