Is this asbestos?

scottwillshaw · Tuesday at 12:53 AM

Just bought a CHB 1972 33’ trawler with Ford Lehman 120 engine and after mooching around in the engine bay I noticed this heat wrap around my exhaust. Considering the boat is from the early 1970’s I’m wondering if this is possibly asbestos related? Kinda concerned as I wanted to replace the exhaust elbow as per American diesel’s recommendations and this would involve having to peel back some of this covering potentially disturbing whatever material this is!

Any advice from you helpful folk would be greatly appreciated especially if you have seen or currently have this kind of heat shield?

I for sure don’t know.
Never heard of an asbestos issue on a 70s rec boat. Did have one in my 1925 house. Removed myself, carefully. But cheaply. Not cheap if you call an asbestos analysis and abatement crew. How old are you? It can be deadly to breathe a bunch of, but it takes like 30 years. Good luck!

How’s your breathing now?

I’m 36 so I’m trying to avoid getting asbestosis in my 60’s!
I’m a merchant seafarer by trade and I’ve heard of older 60’s/70’s era commercial vessels containing asbestos bulkheads/linings etc. not sure if that crossed over into the recreational sector or not?
thought I’d reach out to you kind folk see if anyone had seen something similar on their own boats. Whatever heat wrap this is it certainly looks old enough to be original manufacturer supplied maybe?!

I seem to remember rare cases of mesothelioma 10 years after exposure, don`t be too sure of the 30 year lead time theory.
Australia was a world leader in asbestos production, use, and deaths. We had/have a specialist Dust Diseases Tribunal hearing claims by the afflicted, sometimes on their deathbed It`s not long since we acquired trains and ferries from Asia which came with asbestos in them, so I would not be confident it wasn`t used in the 1970s. When in doubt, get it tested by experts. Fortunately, it looks fairly encapsulated

Get a piece of it tested. Not very expensive and sure is better than breathing it in if it is asbestos. Then if it is get a pro to remove it. Should not be very expensive since it is relatively small area.

Is this asbestos?
