Mercruiser 5.0 engine drain plugs

[wewefirex2x]

I have a 1989 raw water cooled 5.0 mercruiser 200 hp 2 barrel carb engine. I just got it back from the shop and decided to run it to see how it sounded. It's gettin warm but this weekend it is supposed to go below freezing.

I cannot find a diagram or location of where all the drain plugs are so I do not have to antifreeze back through for possibly two nasty days of freezing temps. Please help a novice.

One on each side, lower middle of engine. one on each exhaust manifold, power steering cooler should have one; lower the drive

You should also Pull the Big Hose off the engine's Waterpump,....
There's about a Quart of water hiding There too......

Sometimes its easier to pull the hose off the steering cooler and drain.The plug on it can be a pain in @@%...

lol, laying on top of the engine, getting poked by sharp objects, fiddling with a 5/16 plug by feel only.
