I suggest spraying it with PB Blaster (available at a lot of auto parts 
stores) or Kroil (probably only available from the manufacturer).  Do 
this daily and bang it with a hammer.

I have, on one occasion, had to take the manifold off (remove the carb 
from it first) and out of the boat to remove it.

BTW, there's a picture of my system on 
http://alberg30.org/maintenance/MechanicalPropulsion/Exhaust/ except 
that, in my most recent incarnation, I went with brass/bronze and used a 
hosebarb instead of half pipe nipple at the output end.

Hmmm... Maybe Vetus doesn't make it anymore.  My web searches turn up a 
Centek Vernalift, however.

P.S.  I've got some copper pipe, if anyone wants to make the old 
standpipe system 
(http://alberg30.org/maintenance/MechanicalPropulsion/Exhaust/standpipe.html). 
  Speak up now, though, as I'm getting ready to recycle the copper.
