Technical Specifications
Maximum Angle of Installation: 15° flywheel up or
flywheel down when static; or up to 25° when heeling.
Rotation: Anti-clockwise on flywheel, clockwise on output
gearbox output flange - for use with right hand propeller
in ahead, with 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Classification CF (CD or CE have been superseded by CF).
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 measured at the gearbox output
flange (as coupled 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.
