starving for fuel...plaese help!!!

[themacdadt]

hello, i have a 1979 115hp inline 6cyl. motor has been running great for past 6 months. all of a sudden i was heading back to the ramp after being out all day and it started to loose power. i was running at about 4500 rpms and it bogged dowtn like it was starving for fuel. i backed off the throtle to 3000-3200 rpms and it ran fine. after waiting 10 seconds i gunned it and it took off like normal for about 5 seconds and bogged down again. so to make a long story short it runs fine at mid throtle and below but runs out of fuel at wide open throtle. i have rebuilt the fuel pump, changed all fuell lines, new primmer ball and it still has this problem. checked the fuel pickup in my 9 gal. portable tank and found a air leak in it. fixed that issue and thought for sure that was the problem but took it on the water today and the problem still exists. at wide open throtle the primmmer ball is soft and i can pump it and it picks up rpms, but i cant pump it fast enough to allow for wide open throtle.

if anybody has iny suggestions that can help me i would greatly appreciate it..

thanks in advanced!!! todd

I would check out the fuel pump.Might be getting weak or change out the primer bulb.

check both connections at the motor for the fuel line. I had a boat that would do the same thing and after replacing all of the connections it ran great again.
