sound like you may have a plugged high speed jet on your carburetor

Hard to believe brand new go devil has plugged jets. Just fixed my 10+ year 23 hp go devil; carbon build up in carb.

High speed jets. I agree. Doesn't seem like it should be the case, but that's exactly what it sounds like. If it runs good out of the water, but once you put it in a bind, those jets go to sucking hard. It's amazing, and unfortunate how easy they plug.

Check the oil level in the engine! If you have a low oil level switch on the engine and the level is low, it will die when you lower the engine into the water. Happens to me on a regular basis when I get lazy about checking the oil level.

You can also disconnect the switch and see if the engine operates normally.

They can be real helpful over the phone, give them a call if you can wait. Like others have said it has an auto kill if oil level is below x. Check that first. Can't imagine your carb having issues 5 minutes into its life. Good luck!

Check your fuel fitting connections at the tank and if you have a fuel/water seperator make sure all is tight. The o ring on your tank connection could also be bad.

Check inside the tank itself as well. You might have something blocking the screen on the suction tube.

Bought mine last August, did the EXACT thing....it's actually the cap on the new tanks according to Warren due to emissions etc, changed my cap & I've never had an issue......these guys all make good points however, check O ring in connector, I always carry 2-3 connectors in my boat just in case....worst case, take the cap off and it will run, just gettn starved for fuel.....all the best!!

Is it a long tail? I agree with what the others said to check. Also, could be a faulty mercury switch if it is a long tail.

Appreciate all the help! Problem turned out to be a small leak in the fuel line I didn't catch. The clamps that came on the fuel line were cheap. Replaced them fixed the leak and it runs great. Ran it for around 5 miles today. Hit a large submerged stump and almost broke a rib, thank god for the kill switch
