RC boat accessory for restoring propulsion and steering on small racing and DIY models. The sourcing map RC Boat Propeller pack contains six nylon three-blade propellers built to tolerate knocks and resist corrosion. Will the 40 x 20mm size and 1.9mm mount hole match the drive shaft in use?
⚡ At a Glance
- • Thrust Efficiency: CW three-blade layout with 40mm diameter converts shaft rotation into forward thrust for small hulls
- • Best for: Replacement for small electric or gas-powered RC racing boats and DIY ship model projects
- • Not ideal for: Large-scale or high-speed boats that require metal or specialist hydrodynamic propellers
Nylon 40 x 20mm, clockwise (CW) three-blade propeller with a 1.9mm mount hole. Supplied as a pack of six for RC racing boats and DIY ship models, with impact and corrosion resistance.
Reliable propulsion for small hulls - with CW 3-blade 40mm propeller
Three blades and a 40mm outer diameter translate motor rotation into steady thrust by pushing water rearwards; clockwise (CW) rotation matches CW drive shafts. The 3-blade geometry favours predictable acceleration and handling on small craft.
Restores movement and control for small boats, making the set suitable as direct replacements during races or hobby sessions.
Absorbs impacts and resists corrosion - thanks to nylon construction
Nylon plastic flexes under impact and has inherent corrosion resistance, which reduces the chance of brittle failure after striking debris or grounding. Flexibility also helps the blades recover shape after minor knocks.
Durable behaviour lowers the risk of sudden breakage, so spares last longer between replacements and tolerate rough water conditions.
Straightforward fitting for DIY repairs - with 1.9mm mount hole and standard fitment
Mount hole diameter is specified as 1.9mm; installation involves sliding the propeller onto the drive shaft and tightening the screws to secure it in place. The pack format keeps multiple spares on hand.
Quick swaps at the pond or in the workshop reduce downtime and make routine maintenance faster for hobbyists.

❓ Frequently Asked Questions
Q: What shaft size do these propellers fit?
A: The mount hole diameter is 1.9mm, so confirm the drive shaft measures the same before fitting.
Q: Are these propellers suitable for electric and gas-powered RC boats?
A: Yes, descriptions list use with electronic (electric) or gas-powered RC racing boats and DIY ship projects.
Q: How durable are the propellers?
A: Made from nylon, the blades offer impact resistance and inherent corrosion resistance, helping them absorb shocks from debris or grounding without shattering.
🏆 Our Verdict
Pack suits hobbyists and racers who need practical, easy-to-fit spares for small craft. Nylon three-blade construction combined with a 1.9mm mount makes the set a straightforward, durable replacement option. Robust material and simple fitment reduce downtime and help keep boats operational across multiple outings.
