Mercruiser 3.0 started twice perfectly overfilled the gas now won't start

I'm back. Completely rebuilt the floor. I got it to start the day after I finished the floor. I was happy about that. I planned to take it out to the lake and it won't start. I have spark on all of the plugs, I pulled them and they smell like gas is in there. They are brand new plugs. I checked the fuel filter and it was old and looked ceramic so I replaced it. Still won't start. Not sure what to do next. Anyone have any ideas?

Are you getting spark? You're either getting too much fuel or not enough fire sounds like. If spark, continue trying to start with the throttle wide open, otherwise might need a carb rebuild. Did you do the stringers and transom as well?
