Motor starts but soon after dies out

Put my 15 sport in the water and got 25 yards from he ramp when my 84 60hp johnson sputtered and died. I couldn’t get it started. Luckily, I got a quick tow back to the ramp. Went home and started inspection with the portable tank and fuel lines. All checked out fine. Checked plugs and spark was fine. I can get it started but it soon dies out. If I hold the carbs open I can get to run continuously, but as soon as I let go, the motor dies out. Where should I start my problem solving? Fuel pump?carbs? Any tips would be greatly appreciated. Mahalo!

I'm no outboard mechanic but I'll boost you back to the top.
When you say you can get the motor to run by holding the carbs open do you mean the choke or the throttle? If you have to manually open the choke that could be your problem right there.

Fuel pump has had it? standard omc pump about 45 bucks.
Now if vro system then you may want to consider capping off the system and putting standard fuel pump on (they do not make and after market vro pump so now your talking $250 bucks).Then you would mix you own gas.

No VRO. If you pump the bulb and it runs, then fuel pump. If pumping does no good, you might have an issue. Disconnect the main fuel line @ the carbs and squeeze bulb, does it flow good? If so connect it and see if it fills up the carbs. If so then you either have a carb issue or a reed issue or you blew something up. Do a compression test as well. Your float may have stuck, etc.

I had the same problem recently with a smaller outboard on my 13 sport. After trying every diagnosis known to man, I discovered a small crack in the fuel line connector that was allowing too much air and not enough gas. It was a simple solution after all of the carb work I had done.
