I have a 1981 Mercruiser 350 I/O im having an issue with. I bought the boat 2 months ago from a guy who has had the carb rebuilt and has replaced the rotor, distributor cap, plugs all last year. i took the boat out 4 times. first 2 times had no problems with it. ran great. then the last 2 times i took the boat out it runs great for the first 30 minutes or so out on the water, then engine will start bogging out and dying, eventually not running at all. i try turning it over with a buddy holding throttle open a little and will run for a few seconds and die again.
Any help would be greatly appreciated. thanks
