I am trying to locate an exhaust manifold for my 1989 OMC Cobra Sterndrive
I am trying to locate an exhaust manifold for my 1989 OMC Cobra Sterndrive (2.3L0 engine). I believe the part number is 0986041. Can you locate one for me and if so how much? I am located in the UK. Submitted by: David Cooke
Sorry there is no manifold available; this is obsolete. There is only a racing version available that is built in Australia, cost over here 1700.00 US plus freight.
