Technical Specifications
Maximum Angle of Installation: Maximum 15° flywheel
up or flywheel down when static; or up to 25° when
heeling.
Rotation: Anti-clockwise on flywheel, clockwise on output
gearbox flange for use with right hand propeller in ahead,
on mechanical gearboxes. Hydraulic gearboxes can be left
or right handed.
Fuel: Diesel fuel must conform to EN590 or ASTM D975.
Engine Lubrication: Engine oil must meet API
Classification CF (CD or CE).
Gearbox Lubrication: See gearbox operator’s manual for
the gearbox oil type and capacity.
Oil Pressure: Minimum (tickover) 0.5 bar.
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.
