Offered are TWO world war 2  Continental Aviation 4-cylinder 120 cubic inch [2 liter], air cooled 25hp DIESEL engines, flat 4 opposed configuration ["Boxer" style]. One engine appears to be complete, the other is missing parts [starter, injectors & lines, air cleaners, possibly more]. These are still in their original stainless steel shipping frames, and are war surplus, having come out of 60 years inside storage. Sold as a pair only. The complete engine has all lines and connections still wrapped in original protective storage materials, so it should still be 100% sealed.

I don't know for sure what these were intended for, but are marked as being made for the US Navy. Note that the serial numbers are 1 and 5. In talking with the Continental Aviation unofficial historian, he indicated that with serial numbers that low, they were likely prototype engines. I have been unable to determine exactly what the Navy's intended use was.
Recently a WW2 enthusiast has suggested these were the power plants for portable electrical power generators on US Navy aircraft carriers, used to start bombers. Another person has said that bombers didn't have on-board batteries to start the bomber engines, as the batteries needed to start the 4 huge engines would weigh in at over 1,000 pounds. Leaving the batteries off the airplane would allow another 1,000 pounds of bombs. Hence the need for the starting generator power units. Several historians have suggested these were produced right at the end of the war, and since they were no longer needed, they were declared surplus material, unused. I've been advised that these are probably the only surviving examples in the world, as none of the WW2 museums we've talked with have one.
While this engine has a listed 25hp, being it's a DIESEL engine, the actual torque should be formidable when compared to a gasoline motor. This 2-liter engine could be [with some custom machine work] installed into a VW bug, dune buggy [or a Porsche that's missing a good motor], and perhaps turn the car into a real screamer!
Note: We contacted several US Military museums who have all said they want these, but only if they are donated, because of their budget restrictions. I'm not in the position to donate them, but I'm open to a reasonable offer. These are sitting on my open trailer under a tarp, so local delivery is possible, as long as you have the ability to off-load them. Approximate size of stainless steel shipping frames is 36" X 30" X 30".
Tax write-off? I don't need the tax write-off, but I'm told it may be possible to qualify for a Federal tax write-off if one buys these and donates them to a qualifying museum.
Note to scammers; I'm familiar with all the various scams on Craig's List, so don't even bother asking me to confirm numbers, accept any payment other than cash, etc.
