2003 nitro lx with mercury four stroke 50 hp. Got the boat from a guy who let it sit for two years with gas in system. Added a can of sea foam and half a tank of new gas. Ran fine the first out at 5500 rpm. Second out, ran fine for ten minutes and then wouldn't allow me to go over 3000rpm at load. Runs fine at idle and neutral. Took it to shop and they said that the fuel line was rotted at the bulb and clogging the line fitting and fuel filter. They replaced the bulb, fuel line, fuel line fittings and the fuel filter. Took it out for the third out and it did the same thing, ran wide open for ten minutes and once again didn't allow me to go over 3000 rpm. starts on first try with choke.
