I am having trouble with my 40 HP evenrude, When it is cold it starts and runs great. After it is warmed up and I start it back up, It runs ok, and then Dies, like it is not getting fuel. It will ideal ok and as soon as I give it gas it starts to lunge, Like it revs and then dies revs and dies.

Does anyone have any words of wisdom for me, (besides getting a new motor!)

We have put a new fuel line,
New water pump.
and was just tuned up.

Thanks Shane Snyder
 
Shane check the integrity of the fuel lines. I had a merc motor that did the same thing it turned out that it was sucking air thru a pin hole in the fuel line. Changed out the fuel line and it never did it again. Just a thought
 
We did out a new fuel line on, But I would like to try another one!
It agree it is the fuel system.

We have abuilt in tank, And could be a problem with the pickup inside the tank.

Thanks for the help. I will check that first.
 
Could be water in the fuel if you can hook a tank with fresh gas in it and give it a try it will tell you if it is the fuel.
 
Run new fuel from a clean container. This will eliminate bad fuel, bad hose, and any tank venting problems. If it still acts up, I would start looking at carb issues to make sure the floats aren't messing up. After that, I would look at an ignition coil that could be breaking down once it warms up.

When my Yamaha did that, it was the pick-up in the fuel tank.

Does your priming ball go soft? In my case, I could keep the motor running if I kept pumping the ball, but it would die within about 10 seconds if I quit.
 
I think I should step up and make it right for you. I obviously sold you a lemon. I'll give you my newly rebuilt 35 hp johnson 1982, and I'll take that old junk off your hands.
