The TFCFL 2-Stroke 3.5HP 49CC Outboard Motor is designed for use with various small watercraft, including inflatable boats, fishing boats, and canoes. It features a manual start system, half water-cooling and half air-cooling system, and tiller control for easy maneuverability.

2. Safety Information

WARNING: Failure to follow these safety instructions could result in serious injury or death.

• Always wear a personal flotation device (PFD) when operating or riding in a boat.
• Ensure the motor is securely mounted to the transom before starting.
• Never operate the motor in poorly ventilated areas due to carbon monoxide risk.
• Keep hands, feet, and clothing clear of the propeller when the engine is running or could accidentally start.
• Use the correct fuel mixture as specified in this manual. Incorrect fuel can damage the engine.
• Do not touch hot engine parts during or immediately after operation.
• Always use the flameout switch for immediate shutdown in emergencies.
• Ensure the boat's transom plate height is suitable (≤42cm/16.53in) for this short shaft motor.

5. Setup and Installation

5.1 Unpacking and Inspection

Carefully remove all components from the packaging. Inspect for any signs of damage during transit. If any parts are missing or damaged, contact customer support immediately.

5.2 Mounting the Outboard Motor

The motor is designed for boats with a transom plate height of less than or equal to 42cm (16.53 inches). Ensure your boat meets this requirement.

1. Position the outboard motor on the boat's transom.
2. Tighten the stern plate clamping bolts (refer to Figure 3, item 3) securely to firmly fix the motor to the boat.
3. Verify that the motor is stable and does not wobble.

This image showcases the tail plate clamping bolt for secure motor fixation, the rubber handle cover for a reliable grip, the cooling water outlet for monitoring engine status, and the prevention of warping mechanism to ensure components return to their correct position.

5.3 Fuel Preparation

This is a 2-stroke engine and requires a specific fuel mixture of gasoline and 2-stroke engine oil.

• Use No.92 lead-free gasoline.
• Use a high-quality 2-stroke engine oil.
• Run-in Period (First 10 hours of operation): Mix 25 parts Gasoline to 1 part 2-stroke Engine Oil (25:1 ratio). Use the provided fuel oil mixing bottle for accurate measurement.
• After Run-in Period: Mix 50 parts Gasoline to 1 part 2-stroke Engine Oil (50:1 ratio).
• Always mix fuel in a separate, approved container before pouring into the motor's fuel tank.

6. Operating Instructions

6.1 Starting the Engine

1. Ensure the motor is submerged in water up to the anti-vortex plate (above the propeller).
2. Fill the fuel tank with the correct fuel mixture (refer to Section 5.3).
3. Locate the choke switch (refer to Figure 5). For a cold start, set the choke to the "ON" position. For a warm start, the choke may not be necessary.
4. Locate the starting rope handle (refer to Figure 3, item 1). Pull the starting rope firmly and smoothly until the engine starts. Do not pull the rope to its full extension or let it snap back.
5. Once the engine starts, gradually move the choke switch to the "OFF" position as the engine warms up.

Figure 5: Easy Operation Controls. This image illustrates the throttle lever for acceleration and steering, the infinitely variable speed control for precise adjustment, and the choke switch for starting the engine.

6.2 Tiller Control and Speed Adjustment

The tiller handle provides direct control over acceleration and steering.

• Steering: Rotate the tiller handle left or right to steer the boat.
• Acceleration: Twist the throttle lever on the tiller handle to increase or decrease engine speed. The motor features stepless speed regulation for fine control.
• Clutch: The motor operates with a clutch system. When the engine is running at idle, the propeller will not engage. As you increase throttle, the clutch engages the propeller.

6.3 Stopping the Engine

To stop the engine, reduce the throttle to idle and then press the flameout switch (refer to Figure 3, item 7, and Figure 2) until the engine shuts off.
