RE: wet vs dry exhaust

Marin, I don't know if all marine diesels have cooled manifolds - I just haven't seen any that aren't because the temperatures would get pretty toasty, as in glow in the dark, 3rd degree burn light your boat on fire toasty just like an automotive engine.* The wrap on a dry stack does keep you from getting burned, but it also serves to nearly eliminate E/R radiant heating.
