FOIL DRIVE THREE-BLADE PROPELLER UPGRADE

Are you looking for a bit more torque to get out of the water more easily? Designed to increase thrust at low RPM, the three-bladed propeller hub is an optional upgrade for Foil Drive Assist PLUS units, offering a game-changer for riders pushing the limits of rider weight, board size and foil size. Compared to the standard two-bladed propeller system, the NEW three-bladed propeller system improves performance through the following: Increased thrust at low RPM More torque at low RPM, preventing propeller cavitation under heavy load. More efficient surface riding when the propellers break the surface. A smoother and quieter ride It is specially designed for riders who need more torque at low RPMs, whether due to using a low-volume board, a foil that is smaller or larger than standard, or a heavier rider. We do not recommend using the three-bladed propeller hub for prolonged foiling at full throttle, as this will drain your battery much more quickly and could cause the electronics to overheat and trigger thermal protection mode. The three-blade propeller hub comes with a range of fittings, including two bolt options: standard propeller bolts and the new knurled bolts:

3x M3 30mm 2.5mm standard propeller bolts can be used; these are the same as the propeller bolts used on the 2-blade hub. It is also possible to use 3 M3 30mm 2mm button-top propeller bolts to improve hydrodynamics, although a secondary tool is required. As they are not in the water flow, they do not cause small bubbles to form which then enter the propeller. The small Button Top bolts require a 2 mm Allen key and cannot be used with the 2.5 mm screwdriver supplied as standard with all Foil Drive kits.
