Power Outputs: These comply with EN ISO 8665
propeller-shaft power.
1. Declared powers are at the gearbox coupling (coupling
to the propeller shaft) as per EN ISO 8665, developed
from our standard engine specification, including
gearbox and accessories as detailed in our current
price lists. Additional accessories or alternative
gearboxes may affect the declared powers. Declared
power outputs are subject to the stated tolerance
band.
2. Operation at parameters outside the test parameters
may affect the outputs / powers.
