The Isuzu engine on a thermo king is rated down around 20 HP actually, but the same engine is used in the Isuzu pickup with a different injector pump and puts out somewhere in the neighborhood of 45 if I'm not mistaken. It's been awhile. The pump on these can be turned up to put out about 35 HP ........... It's a small pump, and with the small injectors the economy is phenomenal. Years ago I built two irrigation systems out of these that operated at an unheard of efficiency of 7/10 gallon per hour on a 1/4 mile wheel line. A superb little motor! Before Isuzu they used a Mercedes, and afterward they went to a Yanmar.
