It can be run through the transome but it's a lot of work. The y pipe that the exhaust exits now must be blocked off at the transome so the motor must be pulled. Then it's a mater of ducting the exhaust through the transome. That would be a short list I'm shure there will be more obsticals as you go.

Some boats have a electric switch that selects were the exhoust exits transome or outdrive.

Check the laws in your area in MN the switchable exhaust is not leagal and they watch for it.
