    200 Optimax rough running in gear help

    Help please 2000 200 hp Optimax 2000 Bass Cat was just rebuilt but ran rough before overhaul.
    Replaced plugs and ignition wires. Drained all fuel from tanks. Idles good but when put in gear, starts miss firing and pops/dies. Runs good otherwise. While in gear idle rpm is 560-600. Could I have a defective coil? engine s/n OT089744

    Did you ever have all 12 injectors serviced? Why was the motor rebuilt?

    The injectors were not serviced. The engine was rebuilt do to low compression.
    Thank-you Savage

    Please see the Forum Announcements and Sticky Posts, then update your thread with the Required info. Thanks!

    Was the cause of the "Low Compression" determined? This is extremely important- if we don't learn from History, we're bound to repeat it.
