Default 7.4 drain plugs

1998 scr
7.4 carbed with bravo 3

I drained the engine and manifolds. I can only find 4 blue plastic drain plugs on this engine. Is there more? That's all I can come up with.
Carbed engine not mpi.
Thanks.

Would help if you said where they are located, one on each manifold, one or two on the block, one on the power steering cooler.

May have one on the raw water pump.

One on each manifold, middle bottom. One on each side of the engine block in the middle by oil pan. Couldn't find anything by impeller housing.

What about the power steering cooler? Port side center of engine down low by oil pan, this hose comes from the raw water pump and goes to the t-stat housing.

Now that I know where to look I'll see if I can find it next time down to the boat.
Thanks for the info.
