Operation; Break-In Procedure - Honda BF40D Owner's Manual

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 called out above.
