BREAK-IN (10 HOURS)
1. First 10 minutes of operation — Operate the
engine in gear at fast idle only.
IMPORTANT: Follow this procedure to protect your 2. Next 50 minutes — Operate engine in gear
new outboard during its initial hours of operation.
Careful break-in allows internal engine components
to “seat” properly, resulting in maximum engine per-
formance.
Failure to carefully follow the break-in procedures
can result in engine damage.
below 3500 RPM.
DO NOT hold a constant throttle setting. Change
engine speed every 15 minutes.
With easy planing boats, use full throttle to quickly
accelerate boat onto plane. Immediately reduce
throttle to one-half as soon as the boat is on plane.
BE SURE boat remains on plane at this throttle set-
ting.
During break-in, you must use extra oil. Use a 50:1
(2% oil) fuel/oil mixture in the fuel tank
in addition
to the operation of the oil injection system. After the
break-in period, check the oil tank to see if the oil
level has dropped, indicating oil usage. If the oil lev-
el has not dropped, have your Dealer check the oil
system before using unmixed gasoline in the fuel
tank.
3. Second Hour — Use full throttle to accelerate
boat onto plane, then reduce throttle setting to
three-quarters. BE SURE boat remains on plane at
this throttle setting.
At intervals, apply full throttle for periods of one to
two minutes, returning to three-quarters throttle for
a cooling period.
Perform the 10-Hour break-in procedure with the
boat and engine in the water, using an appropriate
propeller.
Change engine speed every 15 minutes.
DO NOT perform break-in using a flushing device.
DO NOT start-up or run the engine out of the water.
DO NOT leave a running engine unattended.
4. Next Eight Hours
— Avoid
continuous
full
throttle operation for extended periods.
Change the engine speed every 15 minutes.
IMPORTANT: Before the start-up of your new DO NOT exceed recommended maximum engine
engine:
RPM. Refer to Engine Specifications.
•
Read Engine Starting, Engine Stopping, and
Shifting and Speed Control.
•
Perform prelaunch checks of all equipment.
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.
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. Refer
to Shifting and Speed Control.

•
Change the RPM often. Avoid holding a throttle
setting longer than 15 minutes.
