First, I apologize that I do not have the serial number at hand, I am away from my boat at the time. I will post it as soon as I am back at my shop. I am having an issue with the common "spitting and sputtering" on my 2012 250 Pro XS at higher RPMs, 4000 and up. It will start after 2-3 minutes of running and it can be felt by the boat jumping. But, if I stand in it, it runs like a top and quickly hits the usual 5900-6000, but then starts sputtering again if I decelerate to 4000-5000 RPMs. I am running a 28 Bravo I prop and Bob's lower unit on a 2006 Gambler 2200 DC. I changed primer bulbs this past weekend and was quickly educated on the break down of the gray fuel line. The boat is a 2006 and the fuel line is from the factory. All this being said, I am going to replace all fuel line from the tank to the pulse pump, take pulse pump apart and inspect, take the VST off, clean and inspect, and inspect the grommet-slash-rubber gasket on the high pressure pump. My post is more for encouragement at this point, lol, as I have read countless hours on the issue I am having. I will check the plugs and wires also out of habit. The gray line seems the most logical for me at this point. Thanks to everyone on here who freely gives their advise and education to the many begging like myself, lol! I will post my findings soon!
