  • F115 hard start after run

    I live in FL on the Gulf. It seems my 2003 motor has an intermittent problem. After running a while it is a hard start. I pump the fuel bulb and it starts. This does not happen every time. I fish about 3-4 times a week and it may have this problem once every 3 trips. Sometimes when getting the boat up on plane after fishing a while the motor will suddenly lose power, but not stall. I pump the bulb and it gets going again. It has only done this after the season turned hot. I have replaced the filter on the back of the motor and my fuel/water separator filter. Nothing looked bad in either one of those. I have also installed new spark plugs.
    I have check all of my gas line clamps. No gas leak is evident.
    My local dealer has a two week waiting period due to scallop season currently. So I'm trying to be a backyard mechanic if at all possible.
    Thanks for reading my problem.
    Any ideas?

    May be a vapor lock problem which is hard to diagnois, try idling engine for a little while before shutting off to allow it to cool down some to see if helps.
