T&T: T&T Exhaust

[Trainman484848@aol.com]

Hi
 
I build commercial boats (tugs) and all have dry exhaust. The advantages  are 
many if it's a keel cooled system there is no seawater coming into the  
engine so no raw water pump no heat exchangers no wet elbows thus eliminating  the 
maintenance and repair associated with them.In cold climates there is no  
worries of freezing and the chances of sea water getting into your engine  are 
virtually eliminated. There is less chance of exhaust gas finding it's way  into 
the boat and on the right boat It also looks and sounds very  cool.
 
The disadvantages are the space required to run the associated piping  and 
insulation. They can also be noisy not from the discharge but the piping  itself 
if that's not taken into consideration when it's designed. And then  there's 
sometimes a problem with soot and wet oily residue being sent out on  initial 
start up.
 
BTW so far I have not received any reprimand for my black powder post so  
maybe our moderators aren't the hard ass's that they are sometimes portrayed  as.
