Model year
Model year means one of the following things:
(1) For freshly manufactured vessels and engines (see definition of “new propulsion marine engine,” paragraph (1)), model year means one of the following:
(i) Calendar year.
(ii) Your annual new model production period if it is different than the calendar year. This must include January 1 of the calendar year for which the model year is named. It may not begin before January 2 of the previous calendar year and it must end by December 31 of the named calendar year. For seasonal production periods not including January 1, model year means the calendar year in which the production occurs, unless you choose to certify the applicable engine family with the following model year. For example, if your production period is June 1, 2010 through November 30, 2010, your model year would be 2010 unless you choose to certify the engine family for model year 2011.
(2) For an engine that is converted to a propulsion marine engine after being certified and placed into service as a motor vehicle engine, a nonroad engine that is not a propulsion marine engine, or a stationary engine, model year means the calendar year in which the engine was originally produced. For an engine that is converted to a propulsion marine engine after being placed into service as a motor vehicle engine, a nonroad engine that is not a propulsion marine engine, or a stationary engine without having been certified, model year means the calendar year in which the engine becomes a new propulsion marine engine. (See definition of “new propulsion marine engine,” paragraph (2).)
(3) [Reserved]
(4) For engines that are not freshly manufactured but are installed in new vessels, model year means the calendar year in which the engine is installed in the new vessel (see definition of “new propulsion marine engine,” paragraph (4)).
(5) For imported engines:
(i) For imported engines described in paragraph (5)(i) of the definition of “new propulsion marine engine,” model year has the meaning given in paragraphs (1) through (4) of this definition.
(ii) For imported engines described in paragraph (5)(ii) of the definition of “new propulsion marine engine,” model year means the calendar year in which the engine is modified.
(iii) For imported engines described in paragraph (5)(iii) of the definition of “new propulsion marine nonroad engine,” model year means the calendar year in which the engine is first assembled in its imported configuration, unless specified otherwise in this part or in 40 CFR part 1068.
