Rating Standard: All engine data is based on these conditions: barometric pressure - 29.38 in. (746mm) mercury; inlet manifold air temperature - 85°F (29°C); altitude -500 ft. (152 m). Correction of ratings may be necessary for some high altitude or high inlet air temperature applications. Check Waukesha Engine Division Technical Data Book for factors.
** Intermittent Service Rating: This rating is the high-test load and speed that can be applied in special engine applications. Operation should be limited to a maximum of 1,500 hours per year.
Continuous Power Rating: The highest load and speed which can be applied - 24 hours a day, seven days a week - except for normal maintenance. The rating includes operation of the engine at up to 10% overload for two hours in each 24-hour period.
