Richard,
To the best of my knowledge, the engine color for a 73’ 140 was black. The 1968 block was painted green (and this was a K301AS 12 H.P. engine). I am not sure when the exact color change happened, if this was the end of the 68’ run or not. There may have been some early 69’ models also painted green.
The photo on the model info page is a 68’, also verified by the front guard around the hydraulic hook-ups.
I am not sure what eBay 140 you saw, but if the restoration was correct, and the engine was green, it would have more than likely been a 68’. All other years 69’ (I believe the majority of the run) – 74” had black blocks with the exception of the 69’ Patio which had a white block.
Several possibilities exist for the engine in your parts 140 with the green block. Check the bore diameter. Being as how the piston is marked STD, if it is a K301AS 12 H.P. it will check at: 3.38”, and if it is a K321AS 14 H.P. it will check at 3.50”. Judging from your posted photo, it appears to be a 3.50” bore. But please check this to be sure.
I will also note, even though the piston is marked STD, and the cylinder looks good, does not mean it is not original. It may in fact could be, just low hours and repainted. This also could very well be a replacement engine, in which case it may not have been painted at all. The individual doing the install could have painted it green.
