2000 johnson ocean pro 250

Ok here the deal its driving me crazy i put the boat the water and i started right up backed it off the trailer started out of the cove and start increasing the trottle and it start bogging down and cut off so i started it up and started pumping the bulb and it takes off and we get up on plane and ready around for bout 15 mins and come back to netural the motor idles for bout 5-10mins and then startes sputters and cuts off so we start it up and give it gas and it dont want to accelerate just boggs down and cuts off, so i start it again pump the bulb and it does fine.

So pretty much it will run a full trottle if you get it going by pumping the bulb a few time but once u come back to clutch or idle it runs for bout 5mins and cuts off.

So im guessing maybe the fuel pump?

I have replaced all the fuel lines and fuel filter and i have checked for leak and cant see any.

Ant idea of what it might be or how the fix it

thanks

Pumping the bulb is the test for fuel pump.

Yeh as long as the tank vent and filters are clear,
anti-syphon valve at tanks or blockages, what else can it be? You have the correct fuel line right? Too small diameter can cause loss of WOT.

Another quick test is use a portable tank, if the problem continues then its the pump system.
If the pump is pulse hose driven check the line.
Rebuild the carbs?, but it usually comes back to the pump.
