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. Diesel fuel must conform to BS2869-1970 class A1
or A2. The fuel must be a distillate and not a residual oil or blend.
Lubricant:
Engine - engine oil must meet API Classification CF (CD or CE), See section 2 for details
Gearbox - see gearbox operator's manual for the gearbox oil type and capacity
Oil pressure - minimum (tickover) 0.5 bar
Power outputs: These comply with BS EN ISO 8665:1996 crankshaft power
Note: Declared Powers to ISO8665:1996
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 EN ISO 8665:1995 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.
