Break-In Procedure - HONDA marine BF40D Instructions D'utilisation

During Sea Trials
Check the gearshift operation with the gear shift
lever or remote control lever.
Check the motor operation at trolling speed. Use
the minimum amount of the throttle opening
necessary to operate the boat at a safe trolling
speed for 15 minutes.
• PROPELLER SELECTION
Check the engine speed with the boat under way.
Before engine break-in, avoid continuous full
throttle operation (100% throttle opening). Do not
run the outboard motor at full throttle for more than
2 minutes at a time.
MAXIMUM RECOMMENDED ENGINE SPEED:
BF40D: 5,000 – 6,000 min
BF50D: 5,500 – 6,000 min
Make sure that there is no propeller cavitation in a
straight line. There is the possibility of some
propeller cavitation when turning at full throttle with
the motor trimmed out.
After Sea Trials
• CHECK & CLEAN THE OUTBOARD MOTOR
Check that there is no water in the gear oil.
Check that there are no signs of fuel, oil or water
leaks. Repair if necessary.
After running in salty or dirty water, use a flushing
kit to flush the cooling system with clean water.
Run the outboard motor at idle during flushing for
approximately 10 minutes.
Clean the entire outboard motor thoroughly with a
cloth.
Check the outboard motor for external damage,
defects, or cracks.

14. 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 service life.
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
–1
(rpm)
–1 Next 60 minutes:
(rpm)
Run the outboard motor up to a maximum of 4,000 to
5,000 min
Short bursts of full throttle are acceptable but do not
operate the 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.
Serious damage to the engiine may occur in the area
where the lowest temperature becomes 0°C (32°F)
or less, if a cooling system freezes, and warm-up
operation after starting is not performed but a high-
speed cruise is carried out.
