Re: Cracked Exhaust Elbow - Looking for Jerry Rig Help

If it's the Yanmar elbow, mine had a vertical crack on the side in the middle of the 180 degree elbow. The worry is that the crack internaly could allow water to leak back towards the exhaust manifold. Maybe not a problem if the engine at speed and the exhaust carries the water out but at lower rpm could be a concern. All the temporary fixes would probably do ok but I didn't get what kind of leak if any was water or exhaust. Water would just go to the bilge. If it was a mix at that point I'd worry.

Re: Cracked Exhaust Elbow - Looking for Jerry Rig Help

Forget about getting it fixed here unfortunately, we just don't have the skilled welders or fabricators, something I'm desperately trying to address soon. (There is one very distant possibilty, give me a call on 5522564 if interested) I like Hellosailor's suggestion, I have even repaired leaking membrane housings successfully this way

Great advice here. We know this trick and used it in containing damage in extruded spars.
