4. Setup
4.1 Unpacking and Inspection
Carefully remove all components from the packaging. Inspect the motor for any signs of shipping damage. Ensure all parts listed in the packing list are present. If any damage or missing parts are found, contact your dealer immediately.

4.3 Fueling the Motor
The motor uses an integrated fuel tank. Fill the tank with unleaded gasoline (minimum 87 octane). Do not overfill. Ensure the fuel cap is securely fastened after fueling. The motor is designed for a fuel consumption rate of approximately 1 liter per hour.
4.4 Engine Oil
As a 4-stroke engine, it requires engine oil. Refer to the engine block for specific oil type recommendations, typically a 10W-30 or 10W-40 marine-grade oil. Check the oil level before each use and top up as necessary. Do not overfill the oil reservoir.
5. Operating Instructions
5.1 Pre-Operation Checks
- Verify fuel level.
- Check engine oil level.
- Ensure the propeller is clear of any obstructions.
- Confirm the kill switch lanyard is properly attached.
- Check all connections and fasteners for tightness.
5.2 Starting the Engine
- Ensure the motor is submerged in water to the correct depth.
- Attach the kill switch lanyard to yourself or your clothing.
- If the engine is cold, engage the choke.
- Set the throttle to the start position (usually indicated on the throttle grip).
- Pull the starter cord firmly and smoothly until the engine starts.
- Once started, gradually disengage the choke as the engine warms up.
5.3 Throttle Control
The engine speed is controlled by rotating the throttle grip on the tiller handle. Rotate it towards you to increase speed and away from you to decrease speed.

6. Maintenance
Regular maintenance is crucial for the longevity and reliable performance of your outboard motor.
6.1 After Each Use
- Freshwater Flush: If used in saltwater, flush the cooling system with fresh water to prevent corrosion.
- Cleaning: Wipe down the exterior of the motor to remove salt, dirt, and grime.
- Inspection: Check for any visible damage, loose bolts, or fuel/oil leaks.
6.2 Spark Plug Replacement
The spark plug should be inspected periodically and replaced if fouled or worn. A replacement spark plug is typically included with the motor. Refer to the engine specifications for the correct spark plug type and gap.
6.3 Oil Change
Change the engine oil after the first 20 hours of operation, and then every 50 hours or annually, whichever comes first. Use the recommended marine-grade 4-stroke engine oil.
6.4 Propeller Inspection
Regularly inspect the propeller for damage such as bends, chips, or cracks. A damaged propeller can reduce performance and cause excessive vibration. Replace if necessary.

6.5 Storage
For long-term storage, especially during winter, perform the following steps:
- Drain the fuel tank or add a fuel stabilizer.
- Change the engine oil.
- Remove the spark plug and add a small amount of engine oil into the cylinder, then slowly pull the starter cord a few times to distribute the oil. Reinstall the spark plug.
- Store the motor in a dry, well-ventilated area, preferably upright.
7. Troubleshooting
This section provides solutions to common operational issues. For problems not listed here, contact qualified service personnel.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel, stale fuel, fouled spark plug, kill switch engaged, choke not set correctly. | Check fuel level, replace with fresh fuel, clean/replace spark plug, ensure kill switch is disengaged, adjust choke. |
| Engine runs poorly or lacks power | Clogged fuel filter, incorrect throttle setting, propeller damage, low oil level. | Clean/replace fuel filter, adjust throttle, inspect/replace propeller, check/add oil. |
| Excessive vibration | Damaged propeller, loose mounting clamps. | Inspect/replace propeller, tighten transom clamps. |
| Engine overheats | Insufficient air cooling, engine not fully submerged. | Ensure air vents are clear, verify proper submersion depth. |
