Abstract
A marine engine has an internal combustion engine; an exhaust conduit that conveys exhaust gas from the internal combustion engine; a cooling water sprayer that sprays a first flow of cooling water into the exhaust conduit; and a cooling water jacket that conveys a second flow of cooling water alongside the exhaust conduit so that the second flow of cooling water cools the exhaust conduit. The first flow of cooling water and at least part of the second flow of cooling water are merged and then sprayed together into the exhaust conduit via the cooling water sprayer.
