Bought a project boat with a cracked intake/exhaust manifold. The boat is a 91 but I believe the engine is older and by the casting date on the manifold appears to be an 89 engine. Does anybody have the whereabouts of a replacement manifold for a GM 3.0 181 with a yamaha stern drive..... apparently these are very rare. This particular one takes a Rochester carb with hot air choke. Has anyone out there adapted a replacement for a Merc or OMC??
