1. Introduction and Overview
The Haswing Ultima 3.0 is a powerful and efficient electric trolling motor designed for small watercraft such as tenders, inflatables, car toppers, and portable assembly boats. It features a 29.6V LIPO (lithium polymer) battery and a brushless motor, delivering 110 lbs of thrust, comparable to a 4HP petrol outboard. This motor is equipped with stepless adjustable speed control, a magnetic safety lanyard, and a removable LIPO battery for convenient charging. Its design allows for easy tilting in and out of the water, making it suitable for various water depths. The Ultima 3.0 is built for both salt and fresh water use.

5. Setup and Installation
Follow these steps to properly set up your Haswing Ultima 3.0 trolling motor:
- Mounting the Motor:
- Identify a suitable location on your boat's transom for mounting.
- Attach the transom mount bracket (Figure 3) securely to the transom using the provided clamps. Ensure the bracket is tightened firmly to prevent movement during operation.
- The motor features a Level Lock Bracket for secure positioning.
- Adjusting the Angle:
- The angle adjustment bracket (Figure 4) allows for multiple angle adjustment positions. Adjust the motor angle to ensure the propeller is submerged at the correct depth and angle for optimal thrust and maneuverability.
- Installing the Battery:
- The LIPO battery is removable. Carefully insert the charged battery into its designated compartment on the motor head.
- Ensure the battery is fully seated and the connection is secure.
- Connecting the Magnetic Kill Switch:
- Attach the magnetic kill switch lanyard to the motor and clip the other end to your clothing or wrist. This is a safety feature that will immediately cut power to the motor if you fall overboard.

6. Operation
Operating your Ultima 3.0 motor is straightforward:
- Power On: Ensure the magnetic kill switch is in place. The motor's power indicator (LED display) will light up, showing the battery status.
- Mode Selection: Use the selector button (Figure 5) to choose between 1.0HP and 3.0HP modes. The 1.0HP mode is for lower power consumption and extended range, while the 3.0HP mode provides maximum thrust.
- Speed Control: The motor features stepless variable forward and reverse speed control via the tiller handle (Figure 6). Rotate the tiller handle to increase or decrease speed in either direction.
- Steering: The tiller handle allows for 360° steering, providing excellent maneuverability.
- Tilting the Motor: The motor can be easily tilted in and out of the water using the tilt mechanism on the mount. This is useful for navigating shallow areas or when transporting the motor.
- Folding the Handle: For storage or transport, the handle can be folded down.

7. Maintenance
Proper maintenance ensures the longevity and optimal performance of your trolling motor:
- Battery Charging: Charge the LIPO battery using the provided 100V~240V/4A charger. A full charge typically takes 5-6 hours. Always charge the battery in a well-ventilated area and avoid overcharging.
- Cleaning: After each use, especially in saltwater, rinse the motor thoroughly with fresh water to prevent corrosion. Wipe down all surfaces with a clean cloth.
- Propeller Inspection: Regularly inspect the 3-blade propeller (Figure 7) for any damage, entanglement with fishing lines, or debris. The separate fin design helps protect the propeller from impacts. Clear any obstructions carefully.
- Storage: Store the motor in a dry, cool place. If storing for an extended period, ensure the battery is partially charged (around 50%) and stored separately from the motor.
- Connections: Periodically check all electrical connections for corrosion or looseness.
