Electric Hydrofoil Motor Kit D65L161-120kv Waterproof Motor with 4-Blade Propeller

Electric Hydrofoil Motor Kit D65L161-120kv Waterproof Motor with 4-Blade Propeller

The Quanly D65L161-120Kv Motor Kit is optimized for speed and high-RPM efficiency. Featuring a responsive 120Kv motor and the same precision 124mm 4-blade propeller, it delivers excellent top-end performance and smoother cruising for experienced riders. While maintaining strong thrust, its higher Kv rating allows for greater rotational speed under load, making it the ideal choice for lighter builds and riders prioritizing velocity and efficient planing. Housed in rugged anodized aluminum, this integrated kit offers a perfect balance of speed, durability, and seamless integration for your high-performance eFoil.

Notes:

All test data above corresponds to the D65L161 motor kit paired with the 124mm four-blade propeller.
Key Performance Verification: At the rated 48V under full throttle (100%), the system draws 5.47 kW of input power and produces a measured static thrust of 45.6 kgf, which matches the product description of "Thrust: 45.6 Kg at 114A."
Thrust-to-Power Trend: The thrust-to-power ratio (kgf/kW) decreases as throttle and power increase, which is consistent with the general characteristic of propeller-based propulsion systems being more efficient at lower loads.
