Outboard Paddle Board Propeller
Safety Reminder: Water Activities Safety Guidelines
- Before using this product, each passenger must wear a life jacket or similar PFD (Personal Flotation Device) certified by a local authority, and carry a paddle.
- When engaging in activities like paddle boarding or other racing boards, always wear a leash before use.
- Use this product in water deeper than 0.5 meters, and ensure the environment is safe. If the propeller is entangled with weeds, algae, or fishing nets, please immediately turn off the power and clear the debris.
- Never insert fingers or any part of your body into the propeller at any time to avoid injury.
- Non-professionals should avoid paddle boarding or other water activities when waves exceed 0.6 meters, especially in the ocean.
- Individuals with a history of seasickness should not engage in solo water activities like paddle boarding. If you feel unwell, return to shore as soon as possible.
- Do not venture too far from the shoreline alone to prevent unexpected incidents.
- After each use in seawater, rinse the entire unit with fresh water to remove salt and let it air dry in a shaded area to keep the product clean.
- Please use only the original battery specified for this product. Damage caused by other batteries is the user’s responsibility.
- Minors under 18 must use paddle boards with motorized assistance only under adult supervision. Adults should also avoid going out on the water alone; it’s best to go with a companion.
Simple ESC Matching Guide
Voltage (V):
ESC voltage = Battery voltage (e.g., 3S LiPo = 12V, 6S LiPo = 24V).
Current (A):
ESC current ≥ Motor max current + 20-30% safety margin.
Quick Examples:12V, 20A motor → 30A ESC (or higher).
Rule: ESC can handle higher amps than needed, but never lower. Always check motor specs!
