NMMA is excited to announce the launch of the Gasoline Protection Program 

In response to marketplace demands and evolving marine engine technology, the National Marine Manufacturers Association (NMMA) established a licensing program for gasoline fuel additive products. This allows Gasoline Protection ProgramTM (GPP) additive products to be made available at retail outlets and through independent facilities for marine use. The GPP has been implemented in order to assist boaters and manufacturers in identifying fuel additive products which have been formulated to withstand the rigors of use in marine environments. The GPP specification is intended to support the industry in helping provide long term durability and overall consumer satisfaction with marine engines.  Please reference the official announcement here.  For more information, please reference the FAQ here
