OPERATION CHECK LIST
In the Water
OUTBOARD MOTOR INSTALLATION
Check that there are no water leaks from the motor mounting bolt holes.
Check for the balanced weight distribution in the boat.
OUTBOARD MOTOR OPERATION
Check the neutral switch for proper operation.
Turn the combination switch ON and check whether the buzzer sounds twice.
Turn the combination switch ON and check whether the MIL, Alternator indicator light, overheat
indicator light and oil indicator light come ON.
Turn the ignition switch to the START position and check whether the engine starts.
Check the outboard motor for any abnormal noise.
Check to be sure cooling water flows out of the cooling system indicator.
After the engine warms up:
Make sure the motor returns smoothly to idle.
Check idle speed. IDLE SPEED: 650 ± 50 rpm
Snap the throttle and check the engine response.
Check to see that the emergency stop switch functions securely.
LEAKS
Makes sure that there are no leaks from the fuel lines and/or connections. If necessary, repair
immediately.
Check the outboard motor for cooling water/oil leaks. Repair if necessary.
Check the exhaust system for gas leaks.
During Sea Trials
Check the gearshift operation with the 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.
Dual Motors:
Adjust the tie bar length so that the motors toe-
out. Toe-out is when the motors' forward
measurement is wider than the motors' after
measurement. Motors will toe-out (viewed from
the stern) will ensure better boat stability. It is
best if the wakes of two motors joint 20 – 25 m
(66 – 82 ft) stern.
Not all boats will follow this specification.
Consult your boat manufacturer for toe-in or
toe-out recommendation.
PROPELLER SELECTION
Check the engine rpm 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: BF175D/BF200D/BF225D: 5,000 – 6,000 rpm
BF250D: 5,300 – 6,300 rpm
Make sure that there is no propeller ventilation in a straight line. There is the possibility of some
propeller ventilation 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.
