RC boat propeller set designed to convert motor rotation into dependable forward thrust for racing and DIY models. Model builders seeking tough, easy-to-fit spares will find sourcing map RC Boat Propeller useful. Are the size and mounting compatible with your boat's drive shaft?
⚡ At a Glance
- • Thrust Performance: 2-blade clockwise design with 40mm pitch and 30mm diameter converts rotation into steady forward thrust
- • Best for: RC racing boats and DIY ship models requiring quick replacement propellers
- • Not ideal for: Setups needing counter-rotating pairs or non-standard shaft diameters
Three 30 x 10mm nylon propellers with a 3.17mm mounting hole and CW rotation. Nylon construction balances flexibility and corrosion resistance for impact-prone environments.
Reliable thrust – with 40mm pitch and 2-blade CW design
Pitch denotes the theoretical distance advanced per revolution; 40mm pitch combined with a two-blade clockwise layout converts rotational energy into forward thrust while keeping drag low. The 30mm outer diameter and 10mm height define blade size and swept area.
Steady acceleration and brisk top-end speed for small to medium hulls, making the set suitable for racing runs and fast hobby use.
Durability in rough water – with nylon construction
Nylon offers impact resistance and flexibility, absorbing shocks from debris or grounding rather than shattering like rigid plastics or permanently bending like some metals. Inherent corrosion resistance reduces degradation in wet environments.
Fewer catastrophic failures during knocks or shallow-water operation, extending service intervals and reducing the need for emergency replacements.
Straightforward fit and replacement – with 3.17mm mount hole and standard 30mm OD size
A 3.17mm mounting hole allows sliding the propeller onto compatible drive shafts and securing it with the existing screw or fastener arrangement. Outer dimensions of 30 x 10mm identify the physical fit for many small RC boat setups.
Quick field repairs and easy stocking of spares for DIY builds, so model owners spend less time stranded and more time on the water.
✨ The 4 Key Reasons for sourcing map RC Boat Propeller
- Nylon construction – Absorbs impacts and resists corrosion, reducing mid-season prop failures.
- 40mm pitch – Delivers firm forward thrust for brisk acceleration on flat hulls.
- 3.17mm mount hole – Matches common small drive shafts for quick, secure installation.
- Two-blade CW design – Lower drag for higher top speed on single-rotation setups.
