This has happened three times in the last 2 trips. When I first started the motor today it started up fine and idled for about 5-10 minutes. then leaving the dock it started to sputter and barely run. Had to go pump the primer bulb about 15-20 times to get it firm. Ran fine must of the day until i shut it off , it sat for about 30 minutes and then did the same thing. checked the bulb and it was real easy to squeeze, so i pumped it another 15-20 times and th emotor ran fine. Is this a fuel pump starting to go out or is there something else to look at?
