How many cooling system plugs in Merc 350 2008?

[zebramussel1]

I do not have the Engine Manual. How many of the 'Blue Plugs', with the engine water cooling system on a I/O 2008 Mercruiser 350MAG? I have spotted 4, including the one on the Fuel cooling module, however I am hearing there are 7. Where else can I look? or is 4 correct?

There is 2 that go into the side of the impeller housing, Some times they are hard to get to. It depends on what style cooling drain system you have on how many blue plugs there really are. In this link the blue plug number is 16.http://www.mercruiserparts.com/Show...tandard+Cooling+System+(BRAVO)(7+Point+Drain). But if you look over a few engine areas in this link in the standard cooling & water drain links then you will see what I mean about what style drain system. http://www.mercruiserparts.com/selectDocs.asp?doc_nbr=884717003
