Parts for RC boats that convert motor rotation into forward thrust, aimed at restoring propulsion for small racing and DIY craft, sourcing map RC Boat Propeller. Quick installation and impact-resistant nylon allow dependable launches and fewer broken runs. Will the 33mm diameter and 4mm mount match your drive shaft?
⚡ At a Glance
- • Thrust Efficiency: Balanced thrust for small hulls thanks to three-blade clockwise geometry
- • Best for: Hobbyist racers and DIY model builders using small electric or gas RC boats
- • Not ideal for: High-power or large-scale boats that require larger diameter propellers
33mm outer diameter with a 4mm mounting hole and three clockwise blades. Made from PC plastic (nylon) for impact and corrosion resistance.
Reliable forward thrust – with 3-blade clockwise design
Three blades arranged for clockwise rotation translate motor torque into a steady backward flow of water, producing forward thrust efficiently. The CW orientation matches common shaft rotations on small racing and DIY boats.
Stable acceleration and predictable handling suit race practice and casual runs, reducing sudden cavitation or uneven pull.
Impact resistance and longevity – thanks to PC plastic (nylon) construction
Polycarbonate/nylon composition flexes under impact and absorbs shocks from debris or grounding rather than shattering. The material also resists corrosion from fresh and salt water exposure.
Fewer fractured props after light collisions and better durability during repeated use, lowering the frequency of replacements.
Quick fit and replacement – with a 4mm mount hole
Mounts slide onto a 4mm drive shaft and are secured by tightening screws at the hub, following the specified installation steps. The standard hole size matches common shaft dimensions for small RC craft.
Fast on-boat swaps minimise downtime during field repairs and make the propeller suitable as a reliable spare part.

❓ Frequently Asked Questions
Q: How do I know if this propeller fits my boat?
A: Check that the outer diameter of 33mm and the mount hole diameter of 4mm match the boat's propeller clearance and drive shaft. The listing advises verifying specifications before purchase.
Q: What is the propeller made from and is it durable?
A: Made from PC plastic (nylon), the propeller flexes on impact to absorb shocks and resists corrosion, making it suitable for repeated use in fresh or salt water.
Q: Which rotation does the propeller use?
A: Clockwise (CW) rotation is specified, intended for boats that require a CW propeller configuration.
🏆 Our Verdict
Suitable for hobbyist racers and DIY modellers who need a compact, easy-to-fit replacement propeller. Durable PC nylon construction and a three-blade CW design deliver dependable thrust and impact resistance. Cost-effective as a spare part, it should provide solid long-term value through fewer replacements and quick field repairs.
