How do you check the dwell in a 2.3 omc marine engine?

To check the dwell in a 2.3 OMC marine engine, first, connect a digital multimeter or a dwell meter to the ignition system, specifically the positive and negative terminals of the ignition coil. Next, start the engine and allow it to reach operating temperature. The dwell angle should typically be around 30-35 degrees; if it falls outside this range, adjustments to the points or timing may be necessary. Finally, turn off the engine and disconnect the meter after recording the readings.
