Hello, We noticed the bilge filling with water ever so often and discovered a steady drip coming from just above the seawater intake connection only when the engine is running. See pictures. Any thoughts?

If its just above the inputshaft you may have a leaking bellow and the water is coming thru a vent hole
Only other place is the trim wires but thats more of just a drip, not a stream.
You say only when the engine is running? The Bravo raw water pump is engine mounted and under negative pressure so water cant leak out. Noticing the rust by the steering arm you can also have a bad seal, worn steering pin or worn housing
 
The other place it can leak is around the steering pin at the top of the drive gimbal housing. There's a lip seal in there that's supposed to keep the water out of where the steering arm attaches. It would leak when you steer (usually you have the engine running when you're doing this) if it was no good. Especially if there is any play in the pivots.
There might also be some galvanic corrosion in this area. This can pit, soften and otherwise ruin the metal in that area. If the boat is in a marina sitting, this can get quite bad to the point that you need a new drive.
