• These ratings apply at 1,800 rpm when tested under the

specified standard conditions.

• Net power advertised is the power available at the flywheel

when the engine is equipped with fan, air cleaner, muffler
and alternator. No derating required up to 2285 m (7,500 ft)
altitude.

• Based on standard air conditions of 25° C (77° F) and 99 kPa

(29.32 in Hg) dry barometer. Used 35° API gravity fuel having
an LHV of 42 780 kJ/kg (18,390 BTU/lb) when used at 30° C
(86° F) [ref. A fuel density of 838.9 g/L (7.001 lb/gal)].
