Okay, so this boat was working and the fuel pump went out. Had a clogged fuel line as well. Finally, the fuel pump is changed out and new fuel line installed. I went ahead and changed out the fuel pump relay and the automatic fuse while I was at it. I bought them to ensure I wouldnt have to wait if the pump wasnt the only issue. I am now getting fuel through the carb. But it wont fire. Fully charged battery and just tries to start but never does. I thought maybe it was just flooded and waited about an hour, but same thing. Any thoughts where I should go from here?

Just checked for Spark and it had spark in all 6 cylinders. Went ahead and changed out the plugs since they had quite a bit of carbon buildup on them. Other than that, pretty good shape. It wants to start but just doesnt seem quite up to it. ???

It was the 3/8" ID Line from the tank to the fuel pump. It was still loose going into the fuel filter and fuel pump. It fires up now. Must have been sucking lots of air. Idle is a little low however. About 400 RPM out of the water on the hose.
