About 2 years ago in Nicaragua I had the wet exhaust side blow out (there are two sides: a wet and a dry side) and leak hot salt water everywhere. Let me tell you nothing corrodes metal faster than boiling hot salt water. Thinking, I was prepared because I had noticed the decay and searched out some parts back in Mexico, I assumed a couple days of work and I'll have it fixed. No go. I had purchased the wrong size parts! As usual I went to the internet to look for other parts and found that the type of steel I was using wasn't a good choice anyway. After many failed searches in Central America it took someone flying into Nicaragua from the US to bring some nice new 314 stainless parts.
After searching out all the leaks, everything was good. So I decided to pull off the insulation on the exhaust riser just to see how good that side was. It's the dry side of the exhaust before the salt water is injected for cooling. Stupidly I thought, I'm sure its fine and didn't pull of the itchy insulation earlier when I was buying parts for the wet side. Yikes, about 1/2 the thickness had rusted away underneath the insulation! I did a quick estimate and figured that would give me about 500 hours before it would fail. Based on my previous searching, I didn't stand much of a chance getting the parts again without someone flying them in. So I put it off until I could get parts again.
Flash forward to the present and now the time has come. I couldn't easily find the parts in Ecuador or Panama, but the problem is only getting worse. I pulled out the exhaust assembly and took it down to a great machine shop here in Golfito. In about a day and $55 they removed the rusty mess and machined some new stainless for it. The exhaust looks so good I took a picture of it before wraping it back up with insulation. Isn't it sparkly?
