I have a mid 70's l20 HP 4 Cyl Mercruiser Engine in need of an Exhaust Manifold. Wondering what year models and HP Engines Manifolds are interchangeable? Also does anyone know where I may find one?

The 120 is not interchangeable if it has a two
piece manifold. That is that the intake part
bolts on. You can try OSCO or BARR or a mercury
marine dealer.
