Hey guys, new to the forums. Just purchased a 15' runabout, and it has a nice 55hp evinrude on it. 50% of the time it runs perfect, throttles up great and everything. the other 50%, when i open it up it only speeds as if at 1/4 throttle, and you can feel the engine pulsing like a car running out of gas. So, fuel flow problem right? but why would it work 50% of the time perfectly? I put on a new fuel line, thinking the bulb may be shot, but that didn't do it. Also, the bulb doesn't really feel as firm as it should be all the time. Is that cause it is one from fleetfarm, or something else going on? thanks
