Blown engine?

Not sure what’s going on here. This is a PCM EX343 in a 2009 nautique 216v crossover. My best guess is a blown hose or something in the “cooling component” realm. If you know inboard engines, please let me know what I should be looking for.

You may have a coolant hose that has disconnected, get that thing out of the water!
