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:
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
