An engine portion is arranged in the housing between the intake portion and the exhaust portion. A generator is arranged in the tail cone and is operatively connected to the engine portion. A drive shaft extends from the engine portion to the generator. The drive shaft includes a first end coupled to the engine portion, a second end connected to the generator, and an intermediate portion extending therebetween. The intermediate portion includes a cooling passage that extends from the second end toward a terminal end that terminates short of the first end of the drive shaft.
