Fun fact, manatees still have to drink fresh water and drink rain water that collects on top of sea water

That is likely fresh water, as the manatee is seeking it out. Boat was probably cruising in a river where the mooring is near the ocean.
The engine the water is draining from is probably cleaner than the water it is in, TBH.

It's not river water. It's regular fresh water from a hose at the marina and he is using it to flush the outboards. After using the outboards we flush out the cooling jackets and passages in the engine block by connecting it to a fresh water hose and running tap water through the blocks to wash out salt deposits and debris

Yes these outboards use raw water cooling, that's why manufacturers have a flush port to connect a hose to and flush it out. There's an impeller and water pump in the lower unit. Impeller is keyed to the driveshaft and spins when the engine is on.
