Does the 350 mag have 4 or 5 drain plugs to drain the block?

Depends on which 350 and its cooling system
The GM 350 has 2 plugs, one on each side of the block.
Exhaust 2, one on each manifold
If EFI will have one on fuel cooler/module

Were up to 5 now

Then add in 2 more if its a newer Bravo water pump, or maybe only one if not newest. In other words, need to know which what you have

Not sure, picking this boat up next week after a sea trial and I’ll need to winterize it that night.

I’ll just stand on my head and find out.

That's a CAT motor and more then likely it will have a single point drain system. I see a blue plug (I think) on top of the motor, front port side. It may have the air pump drains on the sea water pump. Something like this kind of setup

Hope you get the owners manual with the boat. If not the link below is where the owners manuals can be found. Find one which list ECT for CATs and don't use the non-ECT.
