Hi, My name is JOHN MOORE and I have an ongoing problem with my OMC Cobra 5.0L. If you could take a few minutes to read this and respond, I would really appreciate it. <br /><br />The OMC Cobra outdrive is factory equipment on my 1992 Four Winns Horizon 190. The boat starts and runs great for a short time but soon develops a mysterious problem.<br /><br />The RPM's will slowly drop from full throttle after the boat warms up. The motor sounds a little throatier and feels to be starving for fuel when this occurs. If I put it into neutral, I can rev it up to higher RPM's, but the minute I engage the outdrive it stalls. <br /><br />The boat will eventually move by feathering the throttle, but it wants to continue to stall out. Gradually it will build up RPM's slightly but nothing above 3,000 & it rides really rough. <br /><br />Like I said the engine runs and starts great, just when you put a load on it after it warms up am I experiencing the problem. It is not overheating and I changed the thermostat to be sure. <br /><br />Do you think I should replace the water fuel separator filter? or Fuel Pump itself? Any thoughts would be greatly appreciated. The engine overheating has been eliminated as a cause and the water pump is good. ???????????HELP
