I had a cracked exhaust manifold and searched online for two new ones and found someone who had two OEM mercruiser exhaust manifolds for sale cheap. The two that were on the motor had a part number of 87114BC2 and the new ones have a part number of 860246. Before I bought them I checked online and it said the 860246 manifolds fit on any 305-350 to present, the only difference I see is the new ones I bought do not have the drain plugs in the bottom of the manifolds like the ones that were on the motor, do I need these? The new ones also say mercruiser on them but the ones that were on the motor said nothing, the motor is a 89. Did they not stamp Mercruiser on the older OEM manifols?
