I have a set of 155 mm Propel crank arms with pedals for sale. They fit any Propel drive offered by Native Watercraft and are in nearly new condition. For comparison, Native’s 155 mm crank arm upgrade kit, when available from a Native dealer, costs $99 and includes two crank arms and a crank arm puller (but no pedals).
I am asking $35 (includes free shipping in the continental U.S.) for two crank arms and pedals plus the two bolts for attaching them. This offer does not include a crank arm puller.
