- 5.7L Mercruiser w/ Alpha One gen2
I have a 93 250 EC with a 5.7 Mercruiser Alpha 1 gen 2. Over last winter I rebuilt the Weber 4 barrel carb. Last year it was sucking down the gas and finicky to start cold or hot. This summer it got noticably better fuel economy and gained some WOT rpm. We keep it in a marina on Lake Erie which is 2+ hours from home. This season we were on the boat a little less than last year, the boat would sit for more than 3 weeks a few times. When it would sit for more than a couple weeks it would be very hard to start the first time. It would crank and crank, maybe 30 seconds total until it would start. After that first time after sitting it would usually start right up with a couple pumps on throttle. Also started fine warm. It seemed like the carb bowl was dry and needed to be cranked long enough to fill up. Is this common? Could my mechanical fuel pump be going bad? Would an electric fuel pump help? Thanks guys.
