Break-In (10 Hours) - Evinrude 100 Operator's Manual

BREAK-IN (10 HOURS)

IMPORTANT: Follow this procedure to protect your
new outboard during its initial hours of operation.
Careful break-in allows internal engine components
to seat properly, resulting in maximum engine life
and performance.
Failure to carefully follow the break-in procedures
can result in engine damage.
The engine management module ( EMM ) will auto-
matically supply extra oil to the engine during the
first five hours of operation above 2000 RPM.
Perform the 10-hour break-in procedure with the
boat and engine in the water, using an appropriate
propeller.
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.
IMPORTANT: BEFORE the first start-up of your
new engine:
Read Engine Starting, Engine Stopping, and
Shifting and Speed Control.
Perform prelaunch check of all equipment.
Launch the boat and start the engine according
to the procedures in Engine Starting. AFTER
start-up:
Verify water pump operation often. Look for a
steady stream of water from the water pump indica-
tor. If the stream of water stops, shut off the engine
to prevent damage. Find and correct the cause, or
see your DEALER, before you continue.
Verify shift function by shifting into gear and observ-
ing that the boat moves and that the movement is in
the same direction as the shifter. Refer to Shifting
and Speed Control.
Change engine RPM often. Avoid holding a throttle
setting longer than 15 minutes.
1. First 10 minutes of operation — Operate the
engine in gear at fast idle ONLY.
2. Next 50 minutes — Operate engine in gear
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 boat is on plane. BE
SURE boat remains on plane at this throttle setting.
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.
Change engine speed every 15 minutes.
4. Next Eight Hours — Avoid
throttle operation for extended periods.
Change engine speed every 15 minutes.
DO NOT exceed recommended maximum engine
RPM. Refer to Engine Specifications.
