Many years ago the lobstermen on the Maine coast used automobile
engines in their boats. They used a "keel cooler" consisting of
several lengths of galvanized pipe. the system was fresh water only
and used the original auto water pump. Even used anti-freeze in the
winter time. A much more effective system then a radiator. After all
if you have the whole ocean to cool the engine why use a less
efficient medium?
