    Mercruiser 5.0 MPI 2013. Crank but no start.

    Maybe a video of the engine trying to start may help some too. Maybe try using a timing light at each spark plug wire and coil wire to see if you have continuous in sequence spark.

    5.7Gi-F Updates with some lessons learned.

    Yes it's important to have the blue cap on tight and not damaged in anyway or it will suck air and burn up the impeller. This should be a habit every boater should do in my opinion every time out....It helps let you get to know the whole operating system. (y)
