Re: Mercurey 9.9 Bigfoot HELP!
I've got an 04 big foot on my Mariner. I'm not exactly sure what you are asking. When running normally, there is a water outlet on the starboard side of the engine case. I've had some issues with mine not running, all associated with e 85 and/or water in the fuel. The carb is relatively easy to remove. I'd suggest you remove the carb, and clean all the jets and passages. Alcohol in e85 will absorb water and do odd things to the brass jets. A failed head gasket will result in oil or water being drawn in to the cylinder, resulting in blue or white smoke from the exhaust. The amount of smoke will be relative to the size of the head gasket failure, but will be VERY obvious. Water squirting from areas other that the starboard engine housing COULD be from a blocked passage. There are several online parts suppliers which provide some good diagrams of systems, try a search engine.
