Howdy fellows. I have a 1987 Mercury Black Max 150 that has an issue I can't figure out. It seems to be loading up on fuel at low speeds--like when I have to idle out of a no wake zone, and then go to hit the throttle to come up out of the hole- it just bogs down, just will not go much at all at full throttle. I can put it in neutral, and kick it up to 3 or 4000 rpm for several seconds, then put it in gear and hit it, and then it will jump out pretty good. This makes me think it is just getting too much fuel. Once up on plane , it runs like a scalded dog. I have read earlier posts on this forum about similar problems, and have replaced the fuel line and bulb, and the 2 check valves, and also the fuel pump diaphragm -which did have a little hole in it. Seemed to do better for awhile, but it is back to doing it again. The boat did sit for about a year and probably had ethanol fuel in it at that time ( I have since only been running ethanol free in it and adding startron to it also) I am wondering, could it be that the floats are shot and causing this, or maybe I just need to rebuild the carbs? Any and all thoughts appreciated, Thanks, Gary Lee in Tennessee
