I have a Yanmar 3GM30
that has an exhaust
manifold (about to be replaced) which has the exiting water
side running directly through a cast hole (in the end of the manifold) into the mixing elbow
through a cast hole (usually this happens via a hose leaving the manifold and entering the elbow).
I cannot find an image of this assembly ANYWHERE online including Torreson or Boatswain's locker or any of the major Yanamr distributors.
This bypassing of the external hose is cast into both pieces... and it is not custom built. I am happy to admit that I do not know if the engine
was retrofitted with something after it was bought... but the holes (and bolt holes) on the gas (exhaust) side fit perfectly and I believe it is a Yamar manufactued part.
Any ideas what these parts
might be called so I can order the right manifold tomorrow????
Photo's soon... I'm too damn tiered now.
