Man, that's gonna' be a lot of engineering, really a whole new system
will probably be developed. I don't think you would want to run tubing
from the engine cooling system through the hull to the cat, or add to
the existing load on it. Now you are talking space and resources for a
new cooling system and cat, remembering that a breakdown in a cat
cooling system could be disasterous if unnoticed.. It is going to be
huge, hull design and fit may have to be completely rethunk. Oh well,
think outboard... Sorry to ramble, just thinking out loud...


I don't see the big problem. First of all, you aren't "cooling" the
converter (or particulate filter (as it is called in the diesel). All you
are doing is carrying away the excess heat generated by the exhaust gases
and reaction process. A secondary raw water pump or even a dual output raw
water pump (main to engine heat exchanger, secondary to cat water jacket)
with both exhausting through the current, water cooled exhaust would do it I
think.
