So I pulled hose from tank blew that all out I then re ran the vent because there was a huge bow in the line dipping down the going up causing a trap.. I replaced all plugs and wires and distributor cap.. installed brand new carb and changed fuel filter .. put new fuel
I have a 1987 rinker with a 3.0 mercruiser same year and boat runs great for first hour or two then it will start to bog and not run over idle speed any ideas?
