Volvo Penta 5.7 gxi - can’t find plug location

[techsped]

Trying to replace drain plugs from winterization. I have 1 plug left over and cannot find where it is supposed to go. 4 Plugs are in the back and underneath of both port and starboard manifolds but I’m left with 1 more plug and have no clue where this is supposed to go.. any ideas?

Power steering cooler?

Hard to tell in the photo but maybe at the other end of the exhaust manifold like item number 15.
Maybe start the engine really quick and see where water comes out.

Thank you so much, I did not know that one was a double plug. Back in business!
