Thank You! It’s no good on the flange and thickness of the wall between the cylinder chambers. The motor had water in it for a very long time, previous owner not me… I pulled engine and took it all apart, sent head and block to machine shop. He had to bore it from .20 to .60. I had him look my manifold and riser and he said no good. Rusted to bad

Well, seein's there is no OMC anymore, yer probably gonna have to hunt down a used one,.....

There's a couple of aftermarket outfits that may, or may not offer a replacement,....
Barr is one of 'em,....

A Merc manifold is different, Volvo, I don't know whether it could be adapted,...

Not sure if this is good with the mods or not but I bought a manifold & riser for my 3.0 from ebasicpower but that was a few years ago.
