Operation Break-In Procedure - Honda Marine BF40A Owner's Manual

6. OPERATION
Break-in Procedure
Break-in period 10 hours
Break-in operation allows the moving
parts to wear-in 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 rpm or
10% to 30% throttle opening.
Next 60 minutes:
Run the outboard motor up to maxi-
mum of 4,000 to 5,000 rpm or 50%
to 80% throttle opening. Short
50
bursts of full throttle are acceptable
but do not operate the
motor contin-
uously at full throttle.
Next 8 hours:
Avoid continuous full throttle oper-
ation (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 called out above.
