engine block drain plug size?

[dber]

Anyone know what size wrench to remove the block drain plugs on a 2005 211 330 exclab?

Its a 9/16 wrench on one side and you can use a 7/8 to get the knock sensor out of the other side.

The manifolds are bigger than an inch, but I just use a large cresent wrench for hose so I dont know the exact size offhand.
