							5. PRE-OPERATION CHECK 
1. Check the engine’oil level. 
CAUTION: 
l Engine oil is a major factor affecting engine performance and service life. 
Non-detergent and low quality oils are not recommended. 
l Running the engine with insufficient oil can cause serious engine damage. 
Use Honda 4-stroke oil, or an equiv- 
alent high detergent, premium qual- 
ity motor oil certified t0 meet or 
exceed U.S. automobile manu- 
facturer’s requirements for Service 
Classification SE or SF. (Motor oils 
classified SE or SF will show this 
designation on the container.)

the average temperature in your 
area. SAE low-40 is recommended 
for general, all-temperature use. 
1. Position the outboard motor vertically, and remove the engine cover. 
2. Remove the dipstick and wipe with a clean rag. 
3. Reinsert the dipstick, and check the oil level with the dipstick resting on 
the filler opening (do not screw in). If the oil level is down toward the 
400 cc mark, fill to the 800 cc mark.

							2. Check the fuel level 
Check the fuel gauge and refill the tank if the fuel level is low. 
NOTE: Open the vent knob before removing the fuel filler cap. When the 
vent knob is firmly closed, the cap will be difficult to remove. 
Use any regular grade automotive gasoline (unleaded gasoline is preferred) 
with a pump octane rating of 86 or higher. Never use an oil/gasoline 
mixture or dirty gasoline. Avoid getting dirt, dust or water in the fuel tank. 
CAUTION: Gasoline substitutes are not recommended; they may be 
harmful to the fuel system components. 
Fuel tank capacity: 13 II (3.4 US gal) 
l Gasoline is extremely flammable and explosive under certain conditions. 
Refuel in a well ventilated area with the engine stopped. 
l Do not smoke or allow flames or sparks near the fuel tank and fuel line. 
l Do not overfill the tank and make sure the filler cap is securely closed 
after refueling. 
l Be careful not to spill fuel when refueling. Fuel vapor or spilled fuel 
may ignite. If any fuel is spilled, make sure the area is dry before starting 
the engine.

							3. Check the following items. 
l Check the propeller, the shear pin, and the cotter pin to be sure they are 
secure and undamaged. 
l Check the stern bracket to be sure the motor is securely installed. 
l Check steering handle operation. 
l Make sure you have the tool kit and spare parts with you (P. 26).

							6. STARTING THE ENGINE 
CAUTION: Damage to the water pump, engine components and exhaust 
system may occur if the motor is operated while the propeller is out the 
water. 
1. Connect the fuel line to the tank and outboard motor, as shown. Be sure 
the connectors are securely latched. 
NOTE: 
l Position the fuel tank so the tank fuel line connector is no more than 1 
meter (3.3 ft) below the motor fuel line connector. 
l Do not place the fuel tank more than 2 meters (6.6 ft) away from the 
motor. 
l Be sure that the fuel line is not kinked.

2. Open the fuel cap vent knob 2 to 3 turns. 
3. Squeeze and release the primer bulb until it feels firm, indicating that fuel 
has reached the motor. Check for leaks. 
w If any fuel is spilled, make sure the area is dry before starting 
the engine. Spilled fuel may ignite. 
NOTE: Do not use the primer bulb whiie the engine is running.

6. After starting, be sure water is flowing out of the water check tube. 
CAUTION: If water does not flow out, or if steam comes out, stop the 
engine. Check to see if the screen in the cooling water inlet is obstructed. 
Do not operate the engine until the problem has been corrected. 
7. If the choke was used, push it in gradually as the engine warms up.

							Emergency Starting 
If the recoil starter is not working properly, the engine can be started with the 
spare starter rope in the tool kit. 
1. Remove the engine cover. 
2. Remove the recoil starter by removing the three 6 mm bolts. 
3. Wind the spare rope clockwise around the pulley to start the engine. 
CAUTION: Keep clear of moving parts. 
4. Reinstall the engine cover. 
CAUTION: Do not operate without the engine cover. Exposed moving 
parts could cause injury and water may damage the engine.

							7. OPERATION 
1. Gear Shifting 
The engine has 3 gears: FORWARD, NEUTRAL, and REVERSE. An 
indicator at the base of the gear shift lever aligns with the letters F, N, or R 
on the engine case to show the gear that has been selected. 
Turn the throttle grip to SHIFT to decrease engine speed before moving the 
gear shift lever. 
CAUTION: When operating in reverse, proceed with caution to avoid 
hitting any underwater obstruction with the propeller. 
NOTE: The throttle mechanism is designed to limit throttle opening in 
REVERSE and NEUTRAL. The throttle can be opened to FAST only in 
FORWARD-gear.
