hey guys,
Well it's another year... and same problem. i thought the tech at the marina was going to fix my boat this winter, but he got canned...causwe he sucked.... Anyway... My 2455 has a OMC 351 5.8L with a holley 4 barrel.... When I start her up, she cranks right up... I engage the neutral throttle and she idles up great.... until I get to about 1800 RPM...at that point if I have the engine hatch open, I can hear the Carb making a sucking sound. the more throttle I give her, the more intense the sucking sound, and then eventually at 1800 rpms, she will start backfiring, and if I keep increasing, will eventually backfire and die.... i don't understand what it is... i am about to change the fuel pump... With the engine off, I can go back there and work the throttle lever on the carb and I can see fuel shooting in on the forward side of the carb out of 2 jets...... Anyone go any ideas?? I have changed the filter 3 times, I have cleaned the inline screen.... It appears to be the original fuel pump, so i figure either way it needs to be changed... HELP! I need to get her fixed this week...the in-laws are coming to town, and i need to get them out of the house....
