Information on certifying engines and vehicles with EPA:
EPA maintains a list of remanufacture systems, or “kits”, certified for use with Category 1 and 2 marine diesel engines according to the provisions of 40 CFR Part 1042, Subpart I. Download the list:
- Marine Remanufacture Kit List (Excel) (1 pg; 40K; September 17, 2012)
The above Remanufacture Kit List file on this web page is periodically updated. To have the latest version automatically sent to you join the Marine Remanufacture Kit electronic mailing list (named "marine_reman"). The most current Remanufacture Kit List file is sent to the members of the electronic list as often as once per week depending on the rate of kit certification.
Read additional information on EPA’s Marine Remanufacture Program.
A list of Approved Methods (Remanufacture Kits) for large Category 3 marine diesel engines is maintained by the International Maritime Organization (IMO) as per regulation 13.7.1 of Annex VI of the MARPOL Protocol (Marine Pollution or Protocol of 1978 relating to the International Convention for the Prevention of Pollution from Ships).
