This package includes a Stage 2 PCM calibration, Stage 2 supercharger pulley, and a bolt-on intercooler water re-route upgrade.\u003c\/p\u003e\n\u003cp\u003eThe Stage 2 package is listed to increase engine output by more than 170 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 6000 RPM, giving customers a wider propping range and additional top-speed potential when the boat, prop, conditions, and setup support it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eStage 2 Kit Features\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStage 2 performance upgrade kit for compatible Mercury Racing 662 SCI applications\u003c\/li\u003e\n  \u003cli\u003eStage 2 high-performance PCM calibration\u003c\/li\u003e\n  \u003cli\u003eStage 2 supercharger pulley\u003c\/li\u003e\n  \u003cli\u003eIntercooler water re-route upgrade to increase system pressure and intercooler efficiency\u003c\/li\u003e\n  \u003cli\u003eListed power increase of more than 170 HP under Whipple test conditions\u003c\/li\u003e\n  \u003cli\u003eListed torque increase of more than 130 lb-ft under Whipple test conditions\u003c\/li\u003e\n  \u003cli\u003eListed MPH gains of 6-10 mph, depending on boat setup and conditions\u003c\/li\u003e\n  \u003cli\u003eIncreased horsepower for improved top-speed potential\u003c\/li\u003e\n  \u003cli\u003eIncreased low-speed torque to help reduce plane time\u003c\/li\u003e\n  \u003cli\u003eIncreased low, mid, and high-speed torque for improved acceleration and throttle response\u003c\/li\u003e\n  \u003cli\u003eIncreased spark at low and mid speeds for improved engine efficiency\u003c\/li\u003e\n  \u003cli\u003e6000 RPM limit compared to stock 5400 RPM limit\u003c\/li\u003e\n  \u003cli\u003eDesigned for 91 octane fuel using the (R+M)\/2 rating method\u003c\/li\u003e\n  \u003cli\u003eMaintains stock-style idle, starting, and driveability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Service Process\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe PCM must be removed and sent to Whipple Superchargers for calibration service.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note:\u003c\/strong\u003e This is a performance kit with calibration and hardware components.
