  • Yamaha V6 Firing Order and Which Cylinder is #1

    2002 Yamaha 150 hp OX66 2 Stroke.
    Looked high and low on the forums and shop manual.
    Cannot find firing order and cylinder numbers anywhere.
    Thanks if you can help.

    The sparkplug that is highest on the motor is # 1.

      There are two spark plugs that are the "highest". This is a V-6. So the questions still remain.

        one bank will be about 1" higher than the other due to the offset of the connecting rods.
