							2. Steering 
To turn to the right, swing the steering handle to the left. To turn to the 
left, swing the handle to the right. Boats equipped with a remote control 
steering wheel are 
controlled in the same way as a car. 
For smooth steering, adjust the steering friction bolt so that 
felt when turning.

							3. Cruising 
With the shift lever in the forward 
position F, turn the throttle grip 
toward FAST to increase speed. 
For normal cruising, open the 
throttle about 3/4. 
To hold the throttle at a steady 
setting, turn the throttle friction 
knob clockwise. To free the throt- 
tle grip for manual speed control, 
turn the friction knob counter- 
clockwise. 
NOTE: For best performance, 
passengers and equipment should 
be distributed to balance the boat 
evenly from side to side and parallel 
to the water from front to back.

							4. Tilting the Motor 
Tilt the motor to prevent the propeller and gear case from hitting bottom 
when the boat is beached or stopped in shallow water. 
1. Stop the engine and put the shift lever into NEUTRAL. 
2. Pull the tilt lever toward you, set the lever in the TILT position, and 
raise the engine to either the 32.5” or 72” tilt position. 
3. To return the engine to the normal RUN position, move the tilt lever 
away from you until it stops, tilt the engine slightly, then lower the 
engine slowly. 
CAUTION: Do not transport the motor in the tilted position; it may drop 
suddenly causing damage to the boat or the motor.

							CAUTION: To avoid damaging the motor, use the utmost care when moor- 
ing a boad, especially when its motor is tilted up. Don’t allow the motor to 
strike against the pier or other boats. 
CAUTION: 
TO avoid damaging the motor, never use it as a handle for lif- 
ting or moving the boat.

							5. Battery Charging and Lighting 
The DC receptacle provides a 12 V, 60 W current for 12 V battery charging 
and lighting. The circuit is protected by a 5 A fuse that is accessible by 
removing the engine cover. 
An electrical plug for the DC receptacle is supplied with your motor. Wire 
your charging or lighting cord to this plug. 
B Batteries produce explosive gases. Keep sparks, flames, and 
cigarettes away. To prevent the possibility of creating a spark near the 
battery, connect the charging cords first to the battery, then to the 
outboard motor, and disconnect the charging cords first at the outboard 
motor. 
CAUTION: 
l Connect the positive battery terminal to the positive charging cord. Do 
not reverse the charging cords, or serious damage to the outboard 
motor’s charging circuit and/or battery may occur. 
l When not in use, cover the DC receptacle with the rubber cover to keep 
it dry and clean.

							8. STOPPING THE ENGONE 
1. Turn the throttle grip to SHIFT and move the shift lever to NEUTRAL. 
2. Push the stop button until the engine stops running.

l High altitude operation 
At high altitude, the standard carburetor air-fuel mixture will be excessive- 
ly rich. Performance will decrease, and fuel consumption will increase. 
High altitude performance can be improved by installing a smaller diameter 
main fuel jet in the carburetor and readjusting the pilot screw. If you 
always operate the outboard motor at altitudes higher than 6,000 feet 
‘above sea level, have your authorized Honda Outboard Motor dealer per- 
form these carburetor modifications. 
Even with suitable carburetor jetting, engine horsepower will decrease ap- 
proximately 3.5% for each 1,000 foot increase in altitude. The affect of 
altitude on horsepower will be greater than this if no carburetor modifica- 
tion is made. 
CAUTION: Operation of the outboard motor at an altitude lower than the 
carburetor is jetted for may result in reduced performance, overheating, 
and serious engine damage caused by an excessively l.ean air/fuel mixture.

							9. MAINTENANCE 
Periodic maintenance and adjustment are important to keep the motor in the 
best operating condition. Inspect or service as scheduled below. 
B Shut off the engine before performing any maintenance. If the 
engine must be run, make sure the area is well ventilated. The exhaust 
contains poisonous carbon monoxide gas. 
CAUTION: 
l If the engine must be run, make sure there is water at least 4 inches above 
the cavitation plate, otherwise the water pump may not receive sufficient 
cooling water, and the engine will overheat. 
l To maintain.cooling system efficiency, flush the outboard motor with fresh 
water after each use in salt water. 
l Use only genuine HONDA parts or their equivalent. The use of replacement 
parts which are not of equivalent quality may damage the motor.

							Engine Oil Change 
Drain the oil while the engine is still warm to assure rapid and complete 
draining. 
1. Remove the engine cover. .Remove the drain screw and filler cap, and drain 
the oil. Reinstall the drain screw. 
2. Fill the crankcase with the recommended oil (see page 10) and check the oil 
level with the dipstick resting on the filler opening (do not screw in). Fill to 
the 800 cc mark. 
Oil capacity: 0.8 R (0.85 US qt)

CAUTION: Used motor oil may cause skin cancer if repeatedly left in con- 
tact with the skin for prolonged periods. Although this is unlikely unless 
you handle used oil on a daily basis, it is still advisable to thoroughly wash 
your hands with soap and water as soon as possible after handling used 
oil. 
NOTE: Please dispose of used motor oil in a manner that is compatible 
with the environment. We suggest you take it in a sealed container to your 
local service station for reclamation. Do not throw it in the trash or pour it 
on the ground.

							Gear Oil Check/Change 
Oil Level Check 
Check the oil level when engine is in the vertical position. Remove the level 
screw and see if oil flows out. If no oil comes out, fill through the drain screw 
hole until the oil starts to flow out through the level screw hole. If the.re is 
water in the oil, the water will flow out first when the drain screw is removed, 
or the oil will be a milky color. 
Oil Change 
Remove the level screw and drain screw to drain the oil. Inject oil through the 
drain screw hole until it starts flowing out through the level screw hole. 
Reinstall and tighten the level screw and drain screw securely. 
CAUTION: If water is detected in the oil, the unit should be inspected by an 
authorized Honda dealer. 
Recommended Oil: API standard (G L-4 or G L-5)
