Where an engine manufacturer has no annual new model production period, model year means the calendar year.

(w) Modified part means any aftermarket part intended to replace an original equipment emissions-related part and which is not functionally identical to the original equipment part in all respects which in any way affect emissions, excluding a consolidated part.

(x) New means a personal watercraft engine or personal watercraft the equitable or legal title to which has never been transferred to an ultimate purchaser. Where the equitable or legal title to the engine or personal watercraft is not transferred to an ultimate purchaser until after the engine or watercraft is placed into service, then the engine or watercraft will no longer be new after it is placed into service. A personal watercraft engine or watercraft is placed into service when it is used for its functional purposes. With respect to imported personal watercraft engines or watercraft, the term new means an engine or watercraft that is not covered by an executive order issued at the time of importation, and that is manufactured after the effective date of this regulation or Part which is applicable to such engine or watercraft, or which would be applicable to such engine or watercraft had it been manufactured for importation into the United States.

(y) Nonconformity or noncompliance means that a significant number, determined by the executive officer, of a class of engines, although properly maintained and used, experience a failure of the same emission-related component(s) within their useful lives which, if uncorrected, results in the engines' failure to comply with the emission standards prescribed under title 13, California Code of Regulations, section 2442 (see Table 1, section 200.9 of this Title) which are applicable to the model year of such engines; or a class of engines that at any time within their useful lives, although properly maintained and used, on average does not comply with the emission standards prescribed under title 13, California Code of Regulations, section 2442 (see Table 1, section 200.9 of this Title) which are applicable to the model year of such engines.
