the proper way to do this is to replace the mid housing with the 25", the shift shaft , the drivehaft, and then the water tube. This can get rather costly. The other option is to cut the transom down, but that can upset the balance on the boat.

That's what I said

Have you thought about an offset plate to get the engine away from the boat by around 2ft, this would allow you to use the shorter shaft engine.
