NOTE: THIS SYSTEM REQUIRES A HIGH DEGREE OF TECHNICAL APTITUDE TO INSTALL AND CONFIGURE. YOU MUST CALL AND SPEAK WITH OUR TECH SUPPORT DEPARTMENT BEFORE GETTING A QUOTE.

WARNING! This system is not to be used on emissions regulated waterways. The intent of this system is to allow the running of a catalyzed marine engine without the catalytic converters installed and without triggering any ECU error codes. With the engine operating in this condition, the emissions control system will be rendered inoperative. For this reason, do not operate the vessel on emissions regulated waterways. This system is not legal for any purpose other than testing purposes and not for use on any state or federal waterway.
