    2002 20V 350 MPI Running poorly

    We were surfing and boat started bogging. We stopped to return to the guy in the water, pulled him up and all was good for a couple of minutes then it started bogging again.

    We suspected bad gas so added some 93 and a can of Seafoam and took it out for a drive. It was fine for 3-4 minutes then started bogging again. We let it idle for a few minutes and then accelerated to 20mph then after 1 minute the symptoms returned.

    It idles perfect!

    If we let it idle for a few minutes it will then run fine under load for about a minute then it starts bogging again.

    These symptoms only happen under load and it doesn’t matter if we are going 8mph or WOT.

    Any help is greatly appreciated.

    Thank you

    Check fuel pressure first. And also let us know what motor you have.
