Overview
Replace the stock plastic propeller on your Pro Boat Black Jack 24, Shock Wave 26, or Recoil 26 with the Hot Racing Aluminum 1.6 x 1.6 4mm Propeller. CNC-machined from billet aluminum and balanced for vibration-free operation, this drop-in propeller upgrade delivers more consistent thrust, reduced shaft vibration, and a cleaner overall running experience compared to the factory plastic prop.
The included CNC-machined aluminum conical M4 propeller nut replaces the stock hex nut with a hydrodynamically efficient conical shape, reducing drag through the water for slightly improved top speed and runtime efficiency. A complete prop-and-nut upgrade in one package.
