Mine was cast stainless steel. I did not bother to measure it since it was a perfect fit.

However from memory (I am not on the boat) it wasn’t 12 mm thick.

That is good.
Did you get cast steel elbow with 12 mm thick flange?

Vladimir,

The elbow I received from an eBay supplier was a perfect fit. I did not need to use and gasket sealer.

Hi Eric,

You are correct. That is also a solution. I will try to do that on Monday.

I wrote my original email as a warning to those who has this cast elbow. It is not just simple replacement.

Did anybody use liquid gasket in addition to a metal one for installation of new mixing elbow?

Why don’t you take the elbow to a machine ship and have them mill off 6 mm of the flange?

This is additional information on the thread related to cast stainless steel mixing elbow.

Cast stainless mixing elbow is much better part at very good price. I was very happy when I bought one. But today I tried to install it and I couldn't. Cast part has much  thicker mounting flange. YANMAR mixing elbow has 6 mm thick flange. Cast elbow flange is 12 mm thick. In some cases effective pin length is too short to accomodate thick flange. Pin replacement is risky because corroded pin can easily break.

On my engine the elbow was leaking and one pin corroded so bad that the threads which  protruded from the nut are no longer usful.  I can install fabricated flange without a  problem, but I can't  use cast elbow with thick flange.  I am in Guadeloupe now and I have to fix my engine ASAP.  I have to evaluate my option now. I can grind off part of the flange to 6 mm thick. Or I can buy fabricated elbow that has 6 mm thick flange.  Pin replacement is not an option for me now. Most likely pin beaks if I try to remove it.

I have a question. Should I use liquid gasket in addition to the steel gasket that is normally used for this application? I believe that liquid high temperature gasket should improve sealing.
