Ok ill start from the beginning. Im at a loss. Bought a 2003 24 aftershock got a good deal at 15k has 496 mag with bravo one. Took the boat out fired it up and it would idle for 5 min then die. Found water in the fuel. Took the boat home drained the tank had it cleaned by gretchens in LB they also replaced the low pressure pump and had the injectors cleaned. Next trip idles great starts to get on plain then falls on its face. Took it home replaced filters again put in new high preasure pump and fuel pressure regulator ( the one under the motor mount the cool fuel system. That was a nightmare) then took it out today. Idle great got on plane did about 30mph. Opened it up and back fire miss backbfire bring it down to idle runs great. Shut it down for 20 min fire it back up Start to get on it ran all the way around lake elsinore at 30mph no problems open it up and pop pop miss back fire. Any one had a problem like this?
