I am not a motor guy. I can tear things apart and clean fix and put back together but if you ask me what a part is I wouldn't have a clue. So I have a 2 stroke %hp mercury on my drift boat. Yesterday i was motoring up river after fishing down and it was running fine we stopped at a spot to fish it again, when I started it back up I gave it gas and it died. It would crank up no problem then die when I would give it gas. Today I put it in a tub and it took 4 or 5 pulls to start.(usually starts on the first pull) but then it ran fine. Stopped it and started it 5 times with no issues. Any ideas why it would happen. Want to try to keep this from happening again, we had to row up river about a mile.
