Vortec? V6 Intake Manifold

[McHaggis]

I'm looking for an intake for a 1996 Vortec? V6. This one is in a boat so it's a Merc with a cast iron 2 barrel intake on it that has been cracked. I can only guess that this engine is a mercruiser 4.3L.
I know nothing about these at all but it has 4 vertical bolts down either side. Will consider any intake that will fit including a 4v but not TBI or FI. I'm asking on behalf of an acquaintance hence why I know very little about this.

Any info that will help me track one down including what exactly this engine/intake is would be a huge help.

Thanks in advance.
Stew
