Hi everyone, I recently got this bayliner and although I'm knowledgeable when it comes to engines and that ones modified for boats are not common to me. After fighting with this for a few days I finally got it running after realizing the safety lanyard was gone so I bypassed the switch for the time being. The boat runs great but suddenly had water pouring out of a metal tube in the exhaust manifold and one in the side of the block. I by chance found two brass wingnuts that resemble a petcock for the most part in the glove box. I checked for the hell of it and they threaded into both tubes from some experience I know that they remove plugs etc.. to winterize most boats (I have had outboards that always spent the winter in a basement corner) it ran fine with these in then suddenly I watched the fuel gauge go from full to empty and it stalled and will crank and not start. It was getting dark so I let it be I'm just hoping someone can tell if I was correct on putting the plugs in these ports or did I just murder my engine in some way? Hoping just was a hiccup with the carb being the boat sat outside the last 2 years.
