Hello I am new to boats and need a little guidance. I have recently picked up an 87 bayliner capri with the aq125b. It has a couple issues that i know of and could use some help. First is that the carb was just rebuilt but it will not start and run on it's own without feeding gas manually into carb. I noticed that it is not pumping gas from the bowl but it is full. The 2nd issue is that it drips from an expansion plug on the underside of the exhaust manifold when I have it running. The plug is not a concern and should be an easy fix. My concern is that it drips antifreeze and was wondering if it should have antifreeze in there as I thought only freshwater passed through it and out the back. If it is not suppose to have antifreeze in it, what could cause it? Any help would be greatly appreciated.
