Had boat winterized last year, going to do it myself this year and wondering where these are all located so I don't miss one.

Exhaust manifolds, each side of the engine block, in the "U" of the engine water pump, the water strainer bucket, the inlet hose.

If you're going to continue to do it yourself and don't mind spending a few bucks to make life easy look at getting these. I put them on last year and this years winterization was pretty quick.

There's also two plugs on the front and back of the V-drive.

I would also say get the skidim kit. If you decide not to make sure that you either put the plugs back in and use anti seize. The water will rust the threads if you don't and it makes putting the plugs back in a pain.
