'88 7.4 Drain Plugs

[Sorrento 25]

Mobile marine mechanics are so unreliable. I can't wait for mine to show up anymore and decided to go ahead and do this myself. I found the block drain plugs, removed those, and poked around in there and got plenty of water and crap out, but I couldn't find any on the manifolds. I did find a hose on each that appeared to be the lowest point of the manifold, pulled that, and plenty of water drained. I also pulled the large hose from the bottom of water pump to get some more. Am I missing anything?
