    While diagnosing an EVINRUDE E-TEC 150 H.O. V6, abnormal operation and difficult starting were observed. During diagnostics, multiple fault codes may intermittently appear, including codes related to internal EMM circuitry, which can trigger the “Check Engine” warning and activate the warning horn.

    In most cases, this type of failure should not be attributed to the control unit (EMM) itself. The root cause is more commonly a shorted sensor or a grounded 5-V reference circuit. Therefore, it is recommended to begin troubleshooting by inspecting the entire 5-V sensor circuit directly at the sensors, such as the oil pressure sensor, the I-COMMAND connector, and the TPS (Throttle Position Sensor).

    Just drain the gear oil, hold the horn on, and sing kum ba yah while holding your left foot over your head.
    That should clear the computer for 7:38 minutes or so.

    Gotta love Evinrude e-tec's!!!

    @DogCavalry is your saviour!

    Godspeed gentlemen and good luck.

    I wonder if the 4 perpetual wave motion machine threads were ai scam seeds. Have one friend who thinks ai is Jesus 2.0, have given him tasks to research that quoted old posts on here and the hull truth from. Always wonder if now some of this is to seed results for the Ai output.

    And then half the results turn out to be deep fakes. I ended up watching about 10 minutes of one last week before I cottoned on. They may be trying to generating traffic on certain sites and poke the algorithm.
