Three Blade Propeller Upgrade

"Looking for a little more torque to get out of the water easier?
Designed to increase thrust at low RPM, the Three Blade Propeller Hub is an optional upgrade for Foil Drive Assist PLUS units, for riders pushing the limits of rider weight, board size, and foil size.
Compared to the regular Two Blade Propeller system, the NEW Three Blade Propeller system improves performance by:
  
Increased thrust at low RPM
  
More torque at lower RPM, avoiding propeller cavitation under high load
  
More efficient surface drive when the propellers break the surface
  
A smoother, quieter ride
It is specifically designed for riders who require more low-end torque, whether this is due to using a low-volume board, a smaller or higher aspect foil than usual, or being a heavier rider.
We do not recommend using the Three Blade Propeller Hub for extended efoiling at full throttle, as this will drain the battery much faster and could cause the electronics to overheat, activating thermal protection mode.
The Three Blade Propeller Hubs come with various hardware, offering two bolt options: Standard Propeller Bolts and the new Button Top Bolts:
3x M3 30mm 2.5mm Standard Propeller Bolts can be used, which are the same as the propeller bolts used on the 2-blade hub. Alternatively, 3x M3 30mm 2mm Button Top Propeller Bolts can be used to improve hydrodynamics, requiring a secondary tool. Since they are not in the water flow, they do not create small bubbles that then enter the propeller.
The smaller Button Top Bolts require a 2mm Allen key and cannot be used with your existing 2.5mm Driver, which comes standard with all Foil Drive kits.
