Rating definitions: hp= 0.7355 kW Ratings are based on conditions of 100 kPa, 30% relative humidity at 25°C. M= For applications where use of rated power is less than 10 hours continuous and operation is less than 3000 hours per year. When combined with a correctly matched propeller which allows the engine rated speed to be achieved in a fully loaded vessel state, the reduced-power operation can be at or below 50 rpm of the rated speed. H= For applications where use of rated power is less than 24 hours continuous and operation is less than 4000 hours per year. When combined with a correctly matched propeller which allows the engine rated speed to be achieved in a fully loaded vessel state, the reduced-power operation can be at or below 50 rpm of the rated speed. Fuel rates: Specific gravity 0.835 g/cc, low calorific value 42700 kj/kg [10200 kcal/kg], Cetane No. 45.
