The 20 inch shaft should be easier to find. The 25 inch shafts are often off salt water rigs and will have had more wear.  Jack plates spell trouble.

In my unprofessional opinion, it's not a good idea. I would keep looking for one with a 20" shaft. I think it would be hard to dial in with an extra 5"s of shaft. But to each his own, and I can't think of a reason it wouldn't work, but it's just a lot of extra work and worry when a 20" shaft would have worked when mounted.

Bad idea, way more stress on your transom sir. and your resell value will down the tube.
