Tightened Brackets: The tightened brackets are used to secure the thruster and transoms of the ship so that the thruster will not fall from your boats. High Power Battery Clamp: The clamp is more durable and wear-resistant under high currents. And they have good conductivity. Circuit Breaker Protector: The trolling motor with overload, short-circuit, and under-voltage protection settings can protect wiring and power. Application The trolling motor is suitable for a variety of small watercraft, such as fishing boats, dinghies, and inflatable boats.

And pay particular attention to the safety instructions included. 2. Don't start the motor on the bank. If you want to test the motor, it should be done in the river. 3. Don't use the motor when no water comes out of it, and then check whether the pump impeller or the water outlet is blocked. 4. Do not switch gears too quickly. You should switch from one gear to another. 5. Be sure the switch is in the OFF position before the connection to the battery. 6. Always disconnect power when replacing the propeller, removing debris around the propeller, charging batteries, transporting a boat, or when the motor is not in use. 7. Remember always disconnect from batteries once the motor leaves water as a rotating propeller can cause personal injury. 8. Electrical arcing near the battery could ignite hydrogen gas and cause the battery to explode. 9. Please wash the motor with freshwater, so that it can greatly reduce the possibility of corrosion. 10. All trolling motors have noise. And the noise of this motor is the same as a motorcycle, which is normal. 11. The trolling motor is recommended for thrusting small boats under 200kg/440lbs. 12. You must prepare a boat motor bracket or lifting board on your boat. 13. The battery is not included in the package. 14. Please choose 12V 100A battery so that the maximum power can be guaranteed for 3 hours of continuous operation. 15. Please allow the slight color difference caused by the shooting light and 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
