omc 120 manifold

[mayjean123]

will a omc 120 manifold work on a mercuiser set-up ? what i.m doing is putting a merc out drive off a 165 6cly merc boat on to my 120 omc motor in a pontoon

Are you talking about the exhaust manifold? If ones a 4cyl & ones a 6cyl it definitely won't fit.

I know the 6 won.t fit but when looking the omc and the merc 120 4 cly manifolds they look about the same just was looking to see if someone has done the same change out like changing a omc ouutdive to a merc

The externals on different drive/engine combos are different. A lot of the engine blocks were the same but that is about it.
