IMPORTANT: Observe the following:
• Do not start the engine without supplying water to the
seawater pickup pump (to prevent pump or engine damage).
• Do not operate the starter motor continuously for more than
30 seconds.
• Never shift the drive unit unless the engine is at idle RPM.
Perform the following as appropriate:
Check all items listed in
Operation Chart.
Perform any other necessary checks, as indicated by your
dealer, or specified in your boat owner's manual.
Place the drive unit in full the down/in position.
Place the control handle in neutral.
COLD OR WARM ENGINE
EFI engines require no throttle advance to start. The boat can be
operated after the engine has started and is idling smoothly.
IMPORTANT: If the engine has not been operated for more than
24 hours, Mercury Marine recommends priming the engine oil
system.
NOTE: Engines that have not been started for extended periods
or have had fuel filter changes may not stay running on the first
few initial attempts to start. Do not advance the throttle to keep
the engine running. Continue to restart the engine until it idles
smoothly which means the fuel system is primed. Allow the
engine to warm up to 54 °C (130 °F) before advancing the
throttle. Do not operate at full throttle until the engine reaches an
oil temperature of 60 °C (140 °F).
FLOODED ENGINE
Move control/throttle lever to half throttle. Be prepared to
decrease engine speed to 1000 ‑ 1500 RPM as soon as engine
starts.
STARTING
• Turn key switch to "START." Release key when engine
starts and allow switch to return to "RUN" position.
