So every now and then, after running my boat wide open, then come back to like 3000 rpm, then back to wide open it will give me a cutting out, stumbling issue, like it will be wide open throttle, but it will cut back too 3000 then back to 5100.. But if I go back to like 3000-3500 it runs just fine. Its like its running out of fuel. I have a 502 that was a mpi, but I swtiched it to a carb. I put a dart intake, and a 850 holley dp. I just used the factory sea pump/fuel pump combo and plumbed the carb off this pump. I have 7 pounds of pressure at idle, Im not sure what pressure I have at 5000 as, I cant really pop the hatch at 70 mph..Does anyone think I have a fuel starvation propblem or do you think there is maybe oil in the fuel from that stupid designed fuel/sea water pump..OR do you think maybe its colapsing the fuel hose??

sounds like you have something in your fuel tank finding its way to the fuel pickup

Put an electronic gauge on it, cheap insurance. That's what I'm doing on mine.
