2.6 Power-rating for commercial use

Some units of the range, while having the same set-up of the
above versions can be supplied with calibrations at reduced
power for commercial use.
The power reduction is needed when the engine is used in
harsh conditions or for long continuous periods.
There are four classes and one sub-class of power-rating:
Class A - Leisure Boats: The use at full load is limited to
-
10% of the total period of use. The maximum power can
be used for 1 hour every 10 hours of use. Outside of
periods of use at maximum load, the speed must be
reduced by at least 10% compared to that of maximum
