Diesel Exhaust heat wrap question
Posted by Sracer42@reddit | sailing | View on Reddit | 6 comments
I have this exhaust manifold off my Catalina 30 with a universal M-25XP diesel. I want to unwrap it to inspect the condition. I believe it will have to be rewrapped before re-installation. Can I use the stuff hot rodders use or does it have to be marine grade something $$$?
Thanks in advance

Wrap looks pretty recent
exhaust too ---
Was it leaking?
Sracer42@reddit (OP)
It was leaking and corroded looking where the raw water hose connected to the injection nipple and where the wet exhaust connected to the hose to the water lift. Once I got it removed from the boat it looks like at least some of it is stainless steel - if it all is it's probably good, but the only way to be sure is to remove the wrap.
I don't want to put it back on in unknown condition.
Boat is a 1994 so it's not ancient.

Stainless can get brittle after 30 years of exhaust heat

Yes, that is why I want to unwrap it for inspection. What I can see looks good, but...

I might just not waste that labor/effort
Unless::
The new part costs as much as a whole Marina--
in Miami

Doesn't have to be marine at all. Anything rated to high enough temp will work, actual temps hit around 400F to 600F, and most wraps are good to 1500-2000F.
Do yourself a favor though, if you do wire seizing around it be sure the pointy or twisty bits are not in a place that will snag you later. I've worked around some very stabby exhaust wraps, not fun
