Replacement P40D47 ThreeBlade Propeller for RC Boats with Brushless Motors Overview This replacement P40D47 threeblade propeller is designed specifically for RC boats powered by brushless motors. It restores propulsion and handling when an original propeller is worn, damaged, or lost. Key benefits Reliable replacement: Restores thrust and steering responsiveness so your boat returns to normal operation quickly. Compatible design: Made for use with brushless motor driven RC boats that accept P40D47 style propellers. Stable performance: Threeblade configuration delivers balanced rotation and consistent water flow for smoother running. Easy to install: Direct replacement format that fits common shaft setups used on many brushless RC boat drives. Practical spare: Lightweight and compact to carry as a field spare for outings, races, or regular maintenance. Important attributes Model: P40D47 Blade count: Three blades for improved grip and predictable handling Function: Propulsion paddle for RC boats with brushless motors Fit and compatibility: Intended as a replacement propeller for brushless motor RC boats accepting P40D47 props; verify shaft size and mounting style for compatibility before installation Durability: Built for routine RC boating conditions and repeated use Performance notes Designed to deliver consistent thrust and efficient transfer of motor power to the water. Threeblade geometry helps maintain directional stability and reduces vibration when installed correctly. Suitable for hobbyist use, practice runs, and recreational racing scenarios. Typical use scenarios 1) After impact damage: Swap in this P40D47 propeller to a bent or broken propeller and get the boat back on the water the same day. 2) Race and practice support: Keep as a spare on race day or during intensive practice sessions to reduce downtime caused by propeller wear or damage. 3) and maintenance: Use during routine maintenance or when upgrading drive components on brushless motor RC boats that require a P40D47 replacement prop. Installation tips Confirm shaft diameter and mounting method match the replacement propeller before fitting. Inspect the prop adapter and set screw for secure seating to avoid slippage. Balance and alignment checks after installation improve performance and reduce vibration. This replacement P40D47 threeblade propeller provides a practical, readytofit option to maintain propulsion and handling on brushless motor RC boats.
