    No MTBE in fuel

    My 50 HP Merc hesitates for a second or two and then runs fine for a while. This happens below 1500 RPM in gear. My dealer says it's because the fuel no longer contains MTBE and the engine was designed to use fuels that have MTBE. I say he's is blowing smoke. Is there any truth to this MTBE...

    Merc 135 Optimax stalls then won't start

    I have a 2000 135 optimax that runs rough in neutral 2000-2600 rpm then stalls abruptly(after about 4-5 minutes) and is hard to restart. If i wait awhile it starts and then shuts down again. If running @ 700 rpm there is no problem and it runs smooth. The engine runs so poor that I can't get...
