2 foot deep water can splash up quite high when driven through.
For sure the starter got soaked. Hopefully there are no openings.
Sealed electrical components can take a dunking so it’s hard to say what all is damaged.
Unless the fan blew water onto the coil packs and alternator you should be alright in a couple of days.
It certainly wouldn’t hurt to use compressed air and blow water out of as many valleys on and around the engine as possible to speed up the drying process, but be careful around the alternator.
