[C320-list] Yanmar exhaust architecture

[colloua5 at aol.com]

These part numbers are they from yamar direct ?


Thanks for all the info


on another note .....my muffler box failed, I am going to clean it, re-epoxy the joint where the two meet and then fiberglass mesh the two together on the outside  completing the sealed unit. From what I read the new units seem as poorly designed as the original.


I am contemplating having one made of brass with  soldered joints over the winter, pressure test it and install, the cost should be equivalent to the fiberglass replacement unit

One item to note is hose size. Mine was 1 5/8. 

There is a reverse direction joint between the elbow and mixing elbow. Play with 
this piece and the final orientation.

124070-13520 mixing elbow
128370-13610 elbow
104214-13580 joint

Gasket, I do not have this part number. 

High temp gasket seal - red from NaPa 

Some anti seize compound for on the joint threads. 

That is all I can thing about.

Others please verify the part numbers. I fairly sure.

Itr seems to me that the cooling water exits on the port sode of the engine and 
the exhaust on the starboard side, so some form of connection needs to be made 
between the two. The ‘standard’ Yanmar exhast injection elbow has the water 
entering the exhaust just a few inches from the engine block, i.e., really 
early; mine has the water enetering about 18 inches downstream, hence, 
presumably the need to lag the prt beforehand which receives no cooling effect!
