Hey Guys,
I recently replaced the exhaust elbows and mixers on my Yanmar 4LHA-STPs. The elbows have a thermal jacket on them, that is made of some sort of fiber insulation. Mine are starting to disintegrate, but I put them back on to get me through my next trip. Now I realize that you can't really slip on replacements without taking off the elbow. It's a royal PIA to take off the elbow, so I'd like to avoid that. Two questions:
1. What purpose do those jackets serve?
2. I seem to recall seeing some sort of heat tape at an auto parts store. Would it work for me to pull off the old jackets and wrap the elbows in that tape?
Thanks,
Doug
