This is a brand-new, factory-sealed Pro Boat PRB286010 Replacement Motor Coupler. This heavy-duty metal collet coupler serves as the critical mechanical bridge connecting your brushless marine motor directly to the drive line flex shaft. It locks down tightly using internal grub screw setups to deliver smooth, high-RPM power transfer without slipping or loosening under extreme 3S to 4S battery loads.
