BREAK-IN (10 HOURS)
Launch the boat and start the engine according to
the procedures in Engine Starting.
•
Verify water pump operation often. Look for a
steady stream of water from the water pump indi-
cator. If the stream of water stops, shut off the en-
gine to prevent damage. Find and correct the
cause, or see your Dealer before you continue.
IMPORTANT: 4-Stroke outboards are shipped
without oil in the crankcase. You must add oil to
the crankcase before starting the engine for the
first time. It is recommended you add Evinrude/
Johnson 4-Stroke outboard oil. Refer to Changing
the Oil for acceptable substitute lubricants.
• Verify shift function by shifting into gear and ob-
serving that the boat moves and that the move-
ment is in the same direction as the shifter.
Follow this procedure to protect your new outboard

allows internal engine components to “seat” proper-
ly, resulting in maximum engine performance.
•
Change the RPM often. Avoid holding a throttle
setting longer than 15 minutes.
Check the crankcase oil level often. Add oil if
needed.
