    Looking at a 07 Mainship 43 pilot powered with the Yanmar 6L42STE 440 mph.
    Noted that some batches have had failure issues. Intend to run these engines at low 1400 -1600 RPM as range is desirable over speed. Enjoyed trouble free service on previous Yanmars. Any comments would be appreciated. - Ed

    Mainship did some exhasut elbow runs the wrong way on some installs. Look it over carefully to insure #6 cyli8nder did/can not pick up some water.
