MERCURY RACING 377 SCORPION ECM UPGRADE

Are you wanting more out of your 377 Scorpion? Whipple Superchargers engineers have developed a custom calibration for all 377 Blue Scorpion engines that maximizes the engines power capacity by increasing the RPM limit, increasing spark advance and modifying the fuel curve to give your boat a cleaner transom and a better performing engine. By optimizing the spark curve for 91 or better fuel, Whipple was able to extract 20HP more while not sacrificing stock reliability. Whipple offers many custom calibrations for built and highly modified engines.

*THE STOCK ECM MUST BE SHIPPED TO WHIPPLE FOR RECALIBRATION SERVICES. INCLUDE ALL CHANGES MADE FROM THE STOCK APPLICATION ALONG WITH YOUR RECEIPT AND CONTACT INFO. STANDARD TURN-AROUND TIME IS 7-10 DAYS.
