Engine is 502 MAG, bone stock, 500 hours. Have had the boat for three seasons now and this is the first time this has happened and only on the starboard side. On cold start, there is some colorless/odorless vapor or steam coming from what appears to be the underside of the exhaust manifold. Rubbing the same area, I get a colorless/odorless liquid on my fingers. Seems like water as it is not slippery like an oil or similar. After running the engine for a bit (30-60mins) and starting again I do not see this vapor.
Any/all help is greatly appreciated. I'm assuming it's the exhaust manifold but welcome other opinions on what to check for and/or replace. Video attached below.
