I have a 2003 90 HP 4 stroke Mercury that bogs when I take the throttle beyond 3500 RPM. When this began, the primer bulb was collapsing at the time of the bogging. I took it to the shop and they replaced the anti-siphon valve. I took the boat out to test and it ran great at full throttle for about 15 minutes before it began to bog down again. The primer bulb does not collapse anymore. It defininitely seems like a fuel starvation problem. Someone told me it might be the fuel pump. Any ideas? I just want to get on the lake and pull a tube. Help!
