🛠️ Setup Guide

  1. Select your variant — choose Motor only if you have an existing propeller; choose Motor + Propeller for a complete drive unit. Verify your propeller hub matches the 10mm shaft before ordering.
  2. Mount the motor — secure the 65111 into your foil mast pod or motor mount using the standard 65mm bolt pattern. Route the 12AWG motor wires (900mm) through the mast or board channel, away from the propeller arc and any moving parts.
  3. Connect motor to ESC — connect the 3 motor phase wires to your ESC phase outputs (A-B-C). Rotation direction can be corrected in VESC Tool or by swapping any two phase wires — no motor rewiring required.
  4. Connect ESC to battery — use a high-current connector rated for 100A+ (Firduo 120A–250A waterproof connector recommended). Verify battery voltage is within 14S (58.8V) max. Use an anti-spark switch or pre-charge resistor to prevent connector arcing on connection.
  5. Connect remote receiver to ESC — for UART mode (VESC ESC): connect receiver TX→ESC RX, RX→ESC TX, power from ESC 5V BEC. For PPM mode: connect signal wire to ESC PPM input. UART mode enables full telemetry on the VX3 display.
  6. Configure ESC via VESC Tool — connect via USB, run motor auto-detection wizard for the 65111, set current limits (35A continuous / 140A max burst), configure throttle curve, and set protection thresholds. Contact our support team for a pre-configured setup file for the 65111 + Manatee 100 PRO combination.
  7. Water test at low power — start at 20–30% throttle in calm water. Verify smooth motor operation, check for vibration or unusual noise, and confirm all connections are sealed before increasing to full power.

❓ FAQ

Q1: What is the difference between the 65111 and the 65162 motor?
Both motors share the same 65mm diameter and IP68 waterproof rating, but differ in length and power. The 65111 (111mm length) delivers 2KW peak / 1.5KW continuous — ideal for lighter builds, smaller boards, and riders under 80kg. The 65162 (162mm length) delivers 7.2KW peak / 120A — suited for heavier riders, larger boards, and higher top speeds. Choose 65111 for a lighter, more compact build; choose 65162 for maximum performance.

Q2: What ESC do I need for the 65111?
You need an ESC rated for at least 40A continuous at up to 14S (58.8V). The Firduo Manatee 100 PRO 75V 100A VESC is the recommended pairing — it provides 100A continuous with a waterproof case and full VESC Tool configurability. For a complete pre-matched system, the Firduo 2KW eFoil Kit includes the 65111 motor, Manatee 100 ESC, and VX3 remote at a bundled price.

Q3: Is the 65111 truly IP68? Can I run it continuously underwater?
Yes. The 65111 is rated IP68 — fully sealed for continuous underwater operation in both fresh and saltwater. The motor relies on natural water flow for passive cooling during operation. Avoid running the motor out of water for extended periods at high power, as passive cooling depends on water flow. Brief out-of-water testing at low power is acceptable for connection verification. After saltwater use, rinse with fresh water to remove salt residue.

Q4: What propeller should I use with the 65111?
The 65111 has a 10mm shaft. The Motor + Propeller variant includes a matched propeller optimized for the 65111's power curve. If selecting the Motor only variant, ensure your propeller hub matches the 10mm shaft diameter. Contact us with your build specs (board weight, battery voltage, target speed) for a propeller recommendation.

Q5: Can I buy the 65111 as part of a complete kit?
Yes. The kit includes the motor with additional accessories. For a fully matched drive system, the Firduo 2KW eFoil Kit – Manatee 100 ESC + 65111 Motor + VX3 Remote is the most complete option — all components are pre-matched and tested to work together, saving you the compatibility research and setup time.
