I have a cracked manifold on my 1993 4.3l v6 sterndrive. I talked with the repair shop about retrofitting a mercruiser manifold since the yamaha is virutally impossible to find. Is there a suggested mercruiser manifold replacement that would be cost effective for parts and labor?

I need to do exactly what you did. could you give me a detailed explanation of what you did, parts and all. I have a 1995 Galaxie open bow that had a cracked block and manifolds, we got a new 5.7 motor but obviously the Yamaha manifolds are impossible to find. If i can convert to another manifold, please tell me how. It will save my boat from the scrap yard. Thanks

can you give some insight as to how you did it? Do I need to fabricate parts?

Did you ever get anywhere on this. I have the same problem and am trying to work through this with little success so far.

Please share details! I need to replace my Yamaha manifolds and risers. Unfortunately, the previous owner did not take care of my baby worth a darn
