40 CFR 91.1204 - Furnishing of maintenance and use instructions to ultimate purchaser.
(a) The manufacturer must furnish or cause to be furnished to the ultimate purchaser of each new marine SI engine written instructions for the maintenance and use needed to assure proper functioning of the emission control system.
(b) The manufacturer must provide in boldface type on the first page of the written maintenance instructions notice that maintenance, replacement, or repair of the emission control devices and systems may be performed by any marine SI engine repair establishment or individual.
(c) The instructions under paragraph (a) of this section will not include any condition on the ultimate purchaser's using, in connection with such engine, any component or service (other than a component or service provided without charge under the terms of the purchase agreement) which is identified by brand, trade, or corporate name. Such instructions also will not directly or indirectly distinguish between service performed by the franchised dealers of such manufacturer or any other service establishments with which such manufacturer has a commercial relationship and service performed by independent marine engine repair facilities which such manufacturer has no commercial relationship.
(d) The prohibition of paragraph (c) of this section may be waived by the Administrator if:
(1) The manufacturer satisfies the Administrator that the engine will function properly only if the component or service so identified is used in connection with such engine, and
(2) The Administrator finds that such a waiver is in the public interest.
