3. DURABILITY

The manufacturer of the engine shall supply engine installation and maintenance instructions, which if applied should mean that the engine in normal use will continue to comply with the limits set out in points 2.1 and 2.2 throughout the normal life of the engine and under normal conditions of use. This information shall be obtained by the engine manufacturer by use of prior endurance testing, based on normal operating cycles, and by calculation of component fatigue so that the necessary maintenance instructions may be prepared by the manufacturer and issued with all new engines when first placed on the market. The normal life of the engine is as follows: For CI engines: 480 hours of operation or 10 years, whichever occurs first; For SI inboard or stern drive engines with or without integral exhaust: for the engine category P_(N) 373 kW: 480 hours of operation or 10 years, whichever occurs first, for engines in the category 373 P_(N) 485 kW: 150 hours of operation or three years, whichever occurs first, for the engine category P_(N) 485 kW: 50 hours of operation or one year, whichever occurs first; personal watercraft engines: 350 hours of operation or five years, whichever occurs first; outboard engines: 350 hours of operation or 10 years, whichever occurs first
