I’m replacing a yanmar YSM8 mixing elbow and have the adaptor to connect it to the lifter but my old elbow also has an adaptor on the other side to connect the exhaust hose. I’m no seeing this adapter on any parts list. Is anyone familiar with this one?
Mixing Elbow replacement

What you have on the old mixer is a straight pipe coupling, no doubt originally used because it's cheap as dirt. Perhaps you'd rather have a 1-1/2MNPT x 1-1/2 barb hose fitting in stainless steel? They're available.
I am going to assume your boat is pre 1980's or real early 1980"s as it was the forerunner of the 1GM/1GM10. Is it a flat head single cylinder engine. Not sure where you are located but some parts are still available but not sure about the mixing elbow. Call your Yanmar dealer, identify the engine model along with serial number and the year of the boat.
Dave. His profile says he is in Anderson SC.
I’m guessing down the hill and a wee bit south of you.
Not sure if Mack Boring out of Somerset, NJ as the cover North Carolina but not sure about South Carolina or South Kackalacky. Suggest calling there and if he has any further questions, send me a private message.
I agree. Step it down with a hose barb, not another POS coupling. It's a nice feeling when you get to improve on a PO's work.
Yes, this is from a 1979 YSM8. I’ll check into a barb. Would there be an issue with thread match?
If you have the new elbow home, you could take it to a hardware store and find out for sure what the thread size is.
Is that one of the Ebay stainless steel elbows? I bought one a year or so back.

I checked Niemiec marine and he also said to check the hardware store. I got the adaptor and elbow from Amazon which was supplied by Austral marine. In reality our old elbow does not look bad inside. We are local lake sailors with not extreme use. We had some leak at the connector causing smoke. Since everything was removed we are just replacing.

I'd suggest a Net search. A local hardware store is unlikely to have the part, but they or an industrial supply outfit could check the thread size for you just to be sure.
