INSTALLATION AND PREDELIVERY
INITIAL RUNNING CHECKS
Break-In (10 Hours)
IMPORTANT: Follow this procedure to protect
the outboard during
its
initial hours of operation.
Careful break-in allows internal engine compo-
nents to seat
properly, resulting
in
maximum
engine
life and performance. Failure to carefully
follow
the break-in procedures
can
result
in
out-
board damage.
Run
the outboard
on
25:1
fuel/oil ratio during
break-in.
Perform the 10-hour break-in procedure with the
boat and outboard
in
the water, using
an
appropri-
ate
propeller.
IMPORTANT:
DO
NOT perform break-in using a
flushing device.
DO
NOT start
up
or
run
the out-
board out of the water.
DO
NOT leave a running
outboard unattended.
During the break-in, check water pump operation
often. Look for a steady stream of water from the
water pump indicator.
If the stream of water stops,
shut off the outboard
to
prevent damage. Find and
correct the cause before continuing.
Change engine
RPM
often. Avoid holding a throt-
tle setting longer than
15
minutes.

First 10 minutes
of
operation - Operate the
outboard
in
gear at fast idle
ONLY.
Next 50 minutes - Operate outboard
in
gear
below 3500
RPM.
IMPORTANT:
DO
NOT hold a constant throttle
setting. Change outboard speed every 15 min-
utes.
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.
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-quarter throttle for
a cooling period.
Change outboard speed every 15 minutes.
Next Eight Hours - Avoid continuous
full throttle
operation for extended periods. Change outboard
speed every
15
minutes.
IMPORTANT:
DO
NOT exceed recommended
maximum outboard
RPM.
