Trying to locate the source of a seawater leak. Started out looking for the source of loose rust in the bilge / starboard motor. Rust source was so close it could have bit me. Turbo housing was rusted and pitted as shown in photo. I believe this engine has a dry exhaust manifold. That being true the only source could be the raw water hose that feeds the elbow or a bad exhaust elbow. Any one else run into this? Any ideas where to look. So far I can not find a leak at idle or under load.
Another question, does anyone know if the seawater dumps directly into the exhaust or does it run in a jacket. Id love to see a drawing of the raw water side of the exhaust system.
