Fred mentioned in the previous post on this that he had his elbow treated by Jethot with a ceramic treatment. I don't have time to do that witk the new elbow but what do you think about having the old elbow done for a spare? I was thinking it could be sand blasted or something to clean it up and rotete them every 3 years. Any thoughts on this.

Don, Jet hot used to provide that service when
I had mine done. They would sandblast your stuff so as to save and protect old, irreplaceable parts. Then coat. And they would re coat for free before a year passed if you weren't happy with their finish. But if they get it right, you should never have to have it done again. And it sure can't hurt to send your old elbow to them. Give 'em a call.

Salt or bad fuel
Why are there so many caked up elbow? Ours was running fine for 10 years plus. Is it the salt water (ours is fresh), the low RPM you guys are running, or are you not burning clean fuel? Sorry, don't mean to put salt in your wounds (accidental pun), but I just want to know.

Hardware Sales in Bellingham
has double tapped bushings and all of the black pipe fittings to make a far better elbow than the Yanmar part. Vancouver BC must have a similar store but I don't have a name. It is not too hard to figure out how to make a better exhaust elbow than the factory part. Cost is about $20 and you can forget about the trick coating and a big expense every few years. Just replace parts as needed. The only ones I am worried about are readily available for less than $2 at just about any hardware store.

How about a diagram?
Patrick: How about a diagram for those of us who can follow directions but not create them? P.S. How does coating the outside of the elbow save anything? I thought it was the inside that went.

holes
I've heard that if you clean the inside of the elbow, tiny holes may pierce the divider, and you'll have water water seep into your manifold. Anyone else heard this?

Recommendations for NOT Cleaning Elbow
As for holes developing in the water/exhaust section ny3103 mentioned, I haven't heard about that but I'm not surprised because that metal section is quite thin. I have had parts people caution about cleaning and replacing the elbow because the sidewalls rust out and get so thin you can get a blowout which will make a real mess of the engine room, amongst other things. To avoid a surprise like a blowout I replace my elbow either every other time (clean once then replace the second time) or, at the most, clean twice. This rusting of the wall is something that everybody should be cognizant of.
