Note: Declared Powers to ISO8665:1995
1. The declared powers are at the same engine speed as the ISO 3046 figures. This
speed is the speed related to the outputs / powers shown.
2. Declared powers are at the gearbox coupling (coupling to the propeller shaft) as per
clause 3.2.1 with standard specifications as per our current price lists. Additional
accessories or alternative gearboxes may affect the declared powers.
3. Operation at parameters outside the test parameters may affect the outputs / powers
which in any case are subject to the ISO tolerance bands.
