GPP Licensing Program

GPP stands for Gasoline Protection Program™. The GPP is a rigorous quality licensing program endorsed by the engine manufacturers of the National Marine Manufacturers Association (NMMA). The program ensures that the products registered in the program adhere to high performance standards and are tested to certify that they meet or exceed all of the specifications of the standard. The products in the program are also audited to ensure they maintain their quality. 

The National Marine Manufacturers Association (NMMA) is the nation's leading trade association representing boat, marine engine and accessory manufacturers. Collectively, NMMA members manufacture an estimated 80 percent of marine products used in North America. 

NMMA is a unifying force and powerful voice for the recreational boating industry, working to strengthen and grow boating and protect the interest of its member companies. For more information about the NMMA, visit  NMMA.org

The GPP certified gasoline protection logo provides boat owners with a means to easily identify products that are endorsed by the NMMA and its boat engine manufacturer members. Providing boat owners with the knowledge and product availability to properly care for their engines is of the utmost importance to the NMMA and its members.
