Efoil Motor Kit 48V D65L161-100kv Waterproof Motor with 4-Blade Propeller

The Quanly D65L161-100Kv Motor Kit is engineered for riders who demand maximum thrust and robust low-end power. Centered on a high-torque 100Kv waterproof brushless motor paired with a 124mm 4-blade propeller, this system delivers a proven 46.5 kgf of static thrust—ideal for heavier payloads, quick foiling starts, and superior performance in varied conditions. Its durable hard-anodized housing ensures long-term reliability in marine environments. This complete, plug-and-play kit provides eFoil builders with a trusted, high-thrust foundation for powerful and responsive rides.

Notes:

All test data above corresponds to the D65L161-100Kv 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.
The provided test data does not include underwater performance results for the D65L161-120Kv model.
