Ok. I've read every post on this site ****** back the last two years and can't find anybody with the same exact symptoms. I can run my boat all day at 4200 rpm or less but once I go above 4300 rpm it just bogs down and cuts out. Restarts just fine and runs the same way. It will also shut down if I try to shoot out the hole fast. I've replaced all fuel lines and filters. The fuel pump was replaced about two years ago and seems good. Any answers or suggestions?
