Operation; Break-In Procedure - HONDA marine BF350A Owner's Manual

8. OPERATION

BREAK-IN PROCEDURE

Break-in period: 10 hours
Break-in operation allows the
mating surfaces of the moving
parts to wear evenly and thus
ensures proper performance and
longer outboard motor life.
Break-in your new outboard
motor as follows.
First 15 minutes:
Run the outboard motor at
trolling speed. Use the
minimum amount of throttle
opening necessary to operate
the boat at a safe trolling speed.
Next 45 minutes:
Run the outboard motor up to a
maximum of 2,000 to 3,000 min
(rpm) or 10% to 30% throttle
opening.
Next 60 minutes:
Run the outboard motor up to
maximum of 4,000 to 5,000 min
(rpm) or 50% to 80% throttle
opening. Short bursts of full
throttle are acceptable but do
not operate the outboard motor
continuously at full throttle.
Next 8 hours:
Avoid continuous full throttle
operation (100% throttle
opening). Do not run the
outboard motor at full throttle
for more than 5 minutes at a
time.
For boats that plane easily, bring
the boat up on plane then reduce
the throttle opening to the
specified break-in settings
described above.
