HRSPN1000ME - 42x63mm Pro Brass Prop Al Bullet Nut Drive Dog Tra M41/Spartan

This product is a high‑precision brass propeller system designed for Traxxas M41 and Spartan catamaran RC boats, including a brass propeller paired with a matching bullet‑style prop nut and dog drive adapter. The brass construction of the prop and hardware provides increased mass and corrosion resistance compared with standard aluminum or plastic components, helping to maintain straight tracking and improve thrust efficiency. The 42 × 63 mm prop diameter and pitch are tuned for high‑speed marine performance, and the bullet nut design allows quick installation and secure fastening to the drive shaft. The integrated dog drive adapter ensures positive engagement with the hull’s flex shaft system for efficient power transfer on on‑water runs.

• Brass propeller with 42 mm diameter and 63 mm pitch tuned for Traxxas M41/Spartan performance.
• Brass bullet‑style prop nut for secure fastening and corrosion resistance in marine environments.
• Integrated dog drive adapter mates directly with the drive shaft for positive engagement.
• Heavier brass mass helps stabilize high‑speed runs and resists deflection under load.
• Corrosion‑resistant materials suitable for freshwater and light saltwater use.
• Precision machined for smooth power transfer and minimal vibration.
• Designed as a direct replacement for stock prop hardware on M41 and Spartan boats.
