Break-in procedure
1. For the initial 2 hours:
Allow sufficient idling time (about 5 minutes)
for the engine to warm up after cold engine
starting.
NOTICE
Running at high speed without sufficient
warm-up may cause severe engine dam-
age such as piston seizure.
Always allow sufficient idling time (5 min-
utes) for the engine to warm-up before
running at high speed.
After warming up, run the engine at idling
speed or the lowest in-gear speed for about
15 minutes.
During the remaining 1 hour and 45 minutes,
if safe boating conditions permit, operate the
engine in gear at less than 1/2 (half) throttle
(3000 r/min.).
NOTE:
You may throttle up beyond the recommended
operating range to plane your boat, then imme-
diately reduce the throttle to the recommended
operating range.

the engine in gear at 4000 r/min. or at three-

Safe boating conditions permitting, operate
the engine in gear at desired engine speed.
You may occasionally use full throttle; how-
ever do not operate the engine continuously

zure.

tion, do not operate at wide open throttle
