I have a 2007 3.0 gas engine that seems to have developed a timing issue. Today it didnt want to shut down when I turned off the key, and continued to turn over several times before shutting off. I also had the raw water impeller disentigrate, and the bearing in the pump is destroyed. There is what seems to be raw seawater in the #4 cylinder on the plug. Any helpful advice to steer me in the right direction? Maybe someone has done this before and could give me a heads up! Thanks for you help!
