If the shop ran your boat, then water could be dripping from the engine's water intake. Over a week is a tad long for it to drip, but nothing to be alarmed about. If the boat has been moved or even climbed in/out of you could move it just enough to cause it to drip out. The water intake loops thru the tranny cooler then up front to the water pump in front of the engine, so there is a good amount of water that could leak out before it stops.
welcome to site, enjoy your first inboard.
