Starting The Engine - Mercury 200 Verado FourStroke Operation And Maintenance Manual

3. Turn the ignition key "ON." The fuel pumps will run for approximately five
seconds.
4. Turn the ignition key to the "START" position and release the key. The
ECM controls the activation of the starter. The starter may continue
cranking for up to eight seconds.
NOTE: When priming a drained fuel system, residual fuel may cause the
engine to flare and stall which shortens the engine cranking event.
5. Continue with the ignition key "ON" and "START" sequence until the
engine continues to run.
IMPORTANT: Allow the starter motor to cool for 20 to 30 seconds between full
eight second crank events. Limit the number of events to a maximum of 10 full
eight second cranking events.
6. Once the engine starts, it may run rough at idle for up to two minutes
while the residual air is purged from the fuel system.
7. If the fuel system will not prime within 10 full eight second cranking
events, use the previous procedure Priming the FSM with a Purge Tool
to prime the fuel system.
